In this work, the Eu(III) and Sm(III) coordination polymers {[Eu(2-stp)2(H2O)6]·2(4,4′-bipy)·4(H2O)}, denoted as (1), and {[Sm(2-stp)2(H2O)2]·2(4,4′-bipy)·5(H2O)}n, denoted as (2), (2-stp = 2-sulfoterephthalate and 4,4′-bipy = 4,4′-bipyridine) were synthesized. Different concentrations of these complexes were combined with the polymer matrix of poly(methylmethacrylate) (PMMA) via the electrospinning technology to form a series of Eu@PMMA and Sm@PMMA nanofibers. The morphology, structure, luminescence and magnetic properties of the synthesized materials were investigated by a variety of techniques. The results indicated that the photostability and thermal stability of the composite nanofibers were greatly improved because the PMMA provided a solid environment for the complexes. Moreover, as the incorporation of complexes into PMMA increased, the luminescence intensities were significantly enriched and the emission color coordinates changed with the concentration of the complexes in the PMMA substrate. Color tunability was achieved with the luminescence changing from reddish orange in the bulk state to near-white light in nanofiber stage.

KARA, Hulya/0000-0002-2032-8930 WOS: 000513242600009 Two new Er(III)-cluster-based coordination compounds have been synthesized by hydrothermal technique using monosodium 2-sulfoterephthalate (2-stp) and 4,4 '-bipyridyl (4,4 '-bpy) ligands. Depending on synthetic procedure, monomeric and polymeric Er(III) products, isolated as {[Er(2-stp)(2)(H2O)(6)]0.2(4,4 '-bipy)0.4(H2O)}, 1 and {[Er(2-stp)(4,4 '-bipy)(H2O)](H2O)}(n), 2. Both compounds have been characterized by elemental analysis, FT-IR, UV-visible and single-crystal X-ray diffraction and solid-state photoluminescence. The X-ray structure analyses show that Er atom is surrounded by two 2-stp ligands which have monodentate connection mode forming a monomeric structure in compound 1. However, in compound 2, Er atoms are coordinated by four bridging 2-stp ligands which adopt a hexadentate connection mode to form a central symmetrically dimeric building unit. The photoluminescence spectrums of the compounds have been exhibited intense blue emission for 1 and cyan-blue emission for 2. The band observed in NIR region at 1532 nm (for 1) and 1540 nm (for 2) are the typical Er-III emission. The excellent NIR luminescent properties, indicating their promising potential applications as gain medium materials in optical amplification devices.

A new linear trinuclear MnIII-MnII-MnIII complex 1 has been synthesized and characterized by elemental, spectral, X-ray and magnetic analysis. X-ray diffraction studies show that the central MnII ion is located at a crystallographic inversion center and is triply bridged to the terminal MnIII ions through one methoxide, one syn-syn carboxylate and one hydroxyl oxygen bridges with the short MnIII…MnII distance that is 3.047 A. The intermolecular C-H…O, C-H…π and ring-metal interactions are observed in the hydrogen-bonded assembly of 1. Magnetic studies reveal that the mixed-valence complex 1 has S = 3/2 ground state with antiferromagnetic exchange interactions between MnII and MnIII ions.

C−H···O and C−H···π intermolecular interaction also connect the molecules in the structures which form to 3D structures of 1 and 2. The ligand and metal complexes 1 and 2 were screened for antibacterial and antifungal activities.

Two new tetranuclear [Ni4(L1)4(MeOH)4] (1) and [Ni4(L2)4(EtOH)(MeOH)(H2O)2]·H2O (2) complexes have been synthesized by solvothermal method. We here report the spectroscopic, structural, photoluminescence and magnetic properties of both complexes. Complex 1 and 2 exhibit a cubane-like Ni4O4 structure. All Ni(II) center has a slightly distorted octahedral geometry. The optical properties of 1 and 2 have been analyzed by photoluminescence spectra obtained in the visible region. Variable-temperature (2–300 K) magnetic studies have been analyzed by using the Heisenberg Hamiltonian model with 2J exchange pathways. The best–fit parameters in analysis of the magnetic data are found as J1 = −2.38 cm−1, J2 = +5.43 cm−1, g = 2.2, Nα = 0.08 for 1, J1 = −2.34 cm−1, J2 = +4.90 cm−1, g = 2.2 and Nα = 0.11 for 2. These results are shown dominant ferromagnetic interactions between Ni(II) centers. Finally, the strong luminescence emission of both complexes makes them potentially useful photoactive material in developing optical and electronic materials.

A series of new crystal structures of salts containing 3- and 4-pyridineboronic acid (3- and 4-pba) with chlorometallate have been prepared: [4-pbaH][MnCl2] (1), [4-pbaH][CdCl2], (2), [4-pbaH]2[CuCl4] (3), [4-pbaH]2[PdCl4] (4), [3-pbaH](2)[CdCl4] (5), [3-pbaH][CuCl3(OH2)] (6), and [3-pbaH][PdCl2] (7). In these salts five structural forms for the chlorometallate species are observed: mononuclear square planar [M = Pd (4 and 7)], dimeric square-pyramidal [M = Cu (3)], polymeric square-pyramidal [M = Cu (6)], polymeric trans-edge-sharing octahedral [M = Mn (1), Cd (2)], and polymeric cis-edge-sharing octahedral [M = Cd (5)]. The cyclic R2,2(8) boronic acid dimer is formed in the salt of 1-5. NH center dot center dot center dot Cl2M synthons A have been exploited in 1-4, 6, and 7. Both NH...Cl2M (sythons A) and B(OH)2 center dot center dot center dot Cl2M (sythons B) interactions give rise to a synthon of form I in 6. The uncommon folded conformation of the NH center dot center dot center dot Cl2M (synthons A) are formed in 7. The NH or OH donors and consequent branching of the NH center dot center dot center dot Cl hydrogen-bond network leads to one-, two-, and three-dimensional structures. These structures are further stabilized by CH center dot center dot center dot O and CH center dot center dot center dot Cl and p center dot center dot center dot p stacking interactions.

[Fe(SB)(H2O)]ClO4 and [NEt4]3[Fe(CN)6] react in methanol to give a cis cyano-bridged assembly, 3D [NEt4][Fe(5-ClL1)]2[Fe(CN)6] (5-ClL1H2 = N,N′-bis(5-chlorosalicylidenato)-2,2-dimethyl-1,3-diaminopropane), 1, and a trans cyano-bridged trinuclear complex, [NEt4][Fe(5-ClL2)(MeOH)]2[Fe(CN)6] (5-ClL2H2 = N,N′-bis(5-chlorosalicylidenato)-1,2-diaminopropane), 2, depending on the Schiff base used. Complexes 1 and 2 have been characterized by X-ray analyses and magnetic measurements. The four CN− in the equatorial plane of the [Fe(CN)6]3− moiety bridge four Fe ions each in the cis position, which results in a 3D neutral layered structure giving a [–Fe–NC–Fe–CN–Fe–] linkage for 1. The two CN− in the equatorial plane of the [Fe(CN)6]3− moiety bridge two Fe ions, in the trans position, which results in a hydrogen bonded 2D neutral layered structure for 2. Magnetic studies reveal that complex 1 exhibits weak intralayer ferromagnetic coupling, while complex 2 displays transition to a 3D ferromagnetic order between low-spin Fe(III) and high-spin Fe(III) through the cyanide bridges. Complex 2 further displays frequency-dependent alternating current magnetic susceptibility.

Two alkoxo-bridged copper(II) tridentate Schiff base complexes [{Cu(H2L1)}4] (1) [H2L1 = N-(2-hydroxyethyl)-3,5-di-tert-butylsalicylaldimine] and {Cu(H2L2)}4 (2) [H2L2 = N-(2-hydroxyethyl)-4-methoxysalicylaldimine] have been synthesized and structurally and magnetically characterized. X-ray diffraction studies show that 1 and 2 are tetranuclear alkoxo-bridged copper(II) complexes that contain a rather distorted Cu4O4 cubane core of 4+2 type (four short and two long Cu···Cu distances). The coordination of each copper ion can be described as a distorted square pyramid with one nitrogen and four oxygen atoms from three ligands. Variable-temperature magnetic susceptibility measurements on the two tetranuclear complexes 1 and 2 in the range 2–300 K indicate ferromagnetic exchange coupling between copper(II) centers. The magnetic susceptibility data were analyzed by using a simple two-J model with J′ and J″ representing the magnetic exchange couplings through the short and long Cu···Cu exchange pathways, respectively. The J values were as follows: J′ = +28.7 cm–1 and J″ = +7.8 cm–1 for 1, and J′ = +39.8 cm–1 and J″ = +10.2 cm–1 for 2. The sign and magnitude of the exchange coupling constants were justified on the basis of the structural geometric factors of the bridging Cu(O)2Cu fragments, the overlap of the magnetic orbitals, and DFT calculations.

Binuclear and tetranuclear copper(II) complexes are of interest because of their structural, magnetic and photoluminescence properties. Of the several important configurations of tetranuclear copper(II) complexes, there are limited reports on the crystal structures and solid-state photoluminescence properties of `stepped' tetranuclear copper(II) complexes. A new CuII complex, namely bis{μ3-3-[(4-methoxy-2-oxidobenzylidene)amino]propanolato}bis{μ2-3-[(4-methoxy-2-oxidobenzylidene)amino]propanolato}tetracopper(II), [Cu4(C11H13NO3)4], has been synthesized and characterized using elemental analysis, FT–IR, solid-state UV–Vis spectroscopy and single-crystal X-ray diffraction. The crystal structure determination shows that the complex is a stepped tetranuclear structure consisting of two dinuclear [Cu2(L)2] units {L is 3-[(4-methoxy-2-oxidobenzylidene)amino]propanolate}. The two terminal CuII atoms are four-coordinated in square-planar environments, while the two central CuII atoms are five-coordinated in square-pyramidal environments. The solid-state photoluminescence properties of both the complex and 3-[(2-hydroxy-4-methoxybenzylidene)amino]propanol (H2 L) have been investigated at room temperature in the visible region. When the complex and H2 L are excited under UV light at 349 nm, the complex displays a strong blue emission at 469 nm and H2 L displays a green emission at 515 nm.

Bu çalışma, 4-6 Haziran 2004 tarihleri arasında Cardiff[Galler]'de düzenlenen 5. European Magnetic Sensors and Actuators Conference'de bildiri olarak sunulmuştur. This paper reports a novel vacuum coating plant (VCP) system to prepare magnetic thin films. The first step of this extensive investigation was to evaporate and characterise simple iron films on various substrate in order to understand the process of deposition. The source material evaporated by a resistively heated furnace, which was position under the substrate within the VCP system, contains powdered iron of 99.0% in purity and 1-450 mu m in diameter. The magnetic and structural analysis of the films was achieved by using a vibrating sample magnetometer (VSM) and X-ray diffractometer (XRD), respectively, in order to see the effect of production conditions on the films. The magnetic findings indicate that the films produced on flexible kapton (TM) are anisotropic in the film plane whereas the films deposited on glass substrate indicate comparatively less-well defined anisotropy. All films showed planar magnetic anisotropy irrespective of type of substrate used. Furthermore, when these films are subjected to a bending stress within the VSM, the chances in their magnetic hysteresis loops occur. These results indicate a possible future for this technique to deposit sensing devices for stress detection. X-ray measurements show that the films have a typical body centred cubic (b.c.c.) alpha-iron crystal structure. The chemical compositions of films were confirmed by an inductively coupled plasma atomic emission spectrometry (ICP-AES).

Structural analysis of complex 1 shows that the complex is a centrosymmetric dimer. Each of the Fe(III) ions has a five-coordinate geometry and one oxygen atom bridges two Fe(III) ions to form a mu-oxo structure.

Splenic marginal zone lymphoma (SMZL) is a rare disease. It constitutes less than 2% of lymphoid neoplasms. Chronic antigenic stimulation is frequently blamed in the pathogenesis of extranodal marginal zone lymphomas including SMZL. Chronic hepatitis C is frequently observed in SMZL patients. However these reports are largely from North America and Europe. Data from various countries with different hepatitis prevalence are lacking. In this multicenter cohort study we aimed to find out clinical characteristics of SMZL patients in Turkey including viral hepatitis status and treatment details. Data were gathered from voluntary centers under auspices of Hematolojik Onkoloji Dernegi using a SPSS database. Categorical and continuous data were expressed as ratio (%) and median (range) and they were compared by the Chi-square and Mann Whitney U tests, respectively. Survival analyses were computed by the Kaplan-Meier method. Overall survival (OS) was calculated from diagnosis to the date of mortality of any reason. Patients who did not die at last follow-up were censored at this time for OS computations. Parameters related to survival were investigated by Cox regression univariate and multivariate analyses. 66 patients were reported from 8 tertiary care hematology/oncology centers. The diagnosis of SMZL was established by local hematopathologists. Data on baseline clinical characteristics are presented in table 1. Median follow-up duration was 20.4 months (0.3-208) (23 months for surviving patients). 13 patients died during follow-up. Median OS was not reached. Estimated 6 year survival was 59.5% (Figure 1). Older age, no splenectomy during follow-up, HCV positivity was not observed in any patient in this East Mediterranean/Middle Eastern cohort. However 12.1% HBsAg and 32% HBsAg and/or anti-HBcAg positivities are higher than expected for our population. This finding should be confirmed in a larger cohort. Risk factors associated with worse prognosis were generally similar to those reported in European/North American populations. However, HBsAg positivity has not been reported as a risk factor previously. Figure 1 Overall survival Figure 1. Overall survival Table 1 Baseline characteristics Table 1.

Chiral one-dimensional hydrogen bonded copper(II) complex [Cu(HL1)Cl](2)center dot H2O (1) (HL1 = N-(2-hydroxyethyl)-5-nitrosalicylaldimine) has been synthesized and characterized by elemental analysis, crystal structure analysis and magnetic susceptibility. X-ray diffraction studies show that 1 is a binuclear copper(II) complex with a pair of chlorine atoms bridging the copper atoms in a central Cu2Cl2 core. Each copper(II) atom is five-coordinated in a square-pyramidal environment. Variable-temperature magnetic susceptibility measurements on the a binuclear complex 1 in the range 2-300 K indicate a weak antiferromagnetic coupling between the binuclear copper(II) centers, with J = -0.274 cm(-1) and the magneto-structural correlations are discussed in detail.

Güngör, Elif (Balikesir Author), Two Schiff base ligands (HL1, HL2) and their Co(III) complexes, [Co(HL1)(L1)] (1) and [Co(HL2)(L2)] (2) [where HL1 = 2-((E)-(2-hydroxyethylimino)methyl)-4-chlorophenol and HL2 = 2-((E)-(2-hydroxyethylimino)methyl)-4-bromophenol] were synthesized and characterized using spectroscopic methods. The crystal structures of 1 and 2 have been re-determined by single crystal diffraction at 100K. The ligands and their Co(III) complexes were screened for antibacterial and antifungal activities by the disc diffusion, microdilution broth and single spore culture techniques. The antimicrobial activity of the Co(III) complexes and the free ligands exhibit antimicrobial properties and the Co(III) complexes show enhanced inhibitory activity compared with their parent ligand., Balikesir University Nato-B1-TUBITAK

A new hydrogen-bonded pseudo-dimer, [Mn(III)L1(CH3CH2OH)](2)(ClO4) (1) (L1 = N,N'-bis(2-hydroxy-1-naphthalidenato)-1,2-diaminopropane) has been synthesized and characterized by UV-vis, IR, elemental analysis and crystal structure analysis. The single crystal X-ray diffraction reveals that the structure affords an elongated octahedral MnN2O4 coordination environment, geometry with the four donor atoms of the tetradentate Schiff base in the equatorial plane and with two ethanol molecule in axial positions with Mn-O = 2.265(2) and 2.266(2) angstrom.
