Abstract: A novel (CH3OH)(H2O)5 binary cluster is trapped in a photoluminescent silver(I) coordination polymeric host, [Ag2(bpp)2(H2O)(ssa)·4H2O·CH3OH]n (1, bpp=1,3-bis(4-pyridyl)propane, H2ssa=5-sulfosalicylic acid). The heterohexamer can be viewed as either a D 5 water pentamer with a dangling methanol molecule or a combination of D 4 tetrameric water and methanol–water heterodimer. This well-resolved heterohexamer may behave as a useful model helping us to further understand phase behavior of binary methanol–water system. The luminescent behavior of 1 was also discussed.

Abstract: An unprecedented 2D coordination polymer with unique (3,4)-connected self-catenated topology, arising from the parallel interlocking of 1D loop chains via shared binuclear subunits, were prepared from CdII, 5-nitroisophthalic acid and 4,4′-dipyridylamine. The thermal stability and photoluminescence property as well as the photocatalytic performance of 1 were also examined, and the results indicated that 1 shows photocatalytic activity for dye degradation under UV light.

Abstract: A novel 3D coordination framework [Pb2(hfipbb)2(bpp)]n (1) [H2hfipbb=4,4′-(hexa-fluoroisopropylidene)bis(benzoic acid), bpp=1,3-bis(4-pyridyl)propane] based on inorganic rod-shaped infinite Pb–O–Pb chain is presented, which possesses a new (4,5)-connected network topology and shows high thermal stability and strong photoluminescence at room temperature.

Abstract: A new CdII-coordination polymer, namely, [Cd3(nbtc)2·4H2O] n (1), has been hydrothermally synthesized with in situ generated 5-nitrobenzene-1,2,3-tricarboxylate (nbtc3−) ligand. Single-crystal X-ray diffraction study reveals that compound 1 is constructed from trinuclear CdII clusters and exhibits a previously unknown 2D (3,4,9)-connected (3.42)(32.43.5)(36.411.510.68.8) topology as well as 3D H-bonding pillared architecture. In addition, the photoluminescent property and thermal stability of 1 were also discussed. [Copyright &y& Elsevier]

Abstract: In flexible co-ligand system, the P-handed [Cd(bpb)] n and the M-handed [Cd(pda)] n helical chains interweave mutually into a novel 3D coordination framework with diamondoid skeleton, namely, {[Cd(1,4-pda)(bpb)(H2O)]·H2O} n (1) [bpb=1,4-bi(4-pyridyl)butane , 1,4-H2pda=1,4-phenylenediacetic acid ]. Interestingly, 1D hydrophilic tunnel of 1 acts as a template for the formation of the P-handed 1D helical water chains, displaying molecular recognition and chirality transfer. The photoluminescent property and thermal stability of 1 were also discussed. [Copyright &y& Elsevier]

Abstract: A novel 2D coordination polymer, formulated as [Cd2(Hpimdc)2(bpp)(H2O)] n (bpp=1,3-bis(4-pyridyl)propane, H3pimdc=2-propyl-4,5-imidazoledicarboxylate), has been hydro-thermally synthesized and structurally characterized, which shows unusual multifarious helical structures and (3,4)-connected network with (4.82)2(42.83.10) topology. The photoluminescent property and thermal stability of 1 were also discussed. [Copyright &y& Elsevier]

Abstract: Circular and rhombic tubular building blocks interweave mutually into a novel 2-fold interpenetrated 3D PtS framework [Zn(ADB)(H2O)] n (1) (H2ADB=azobenzen-4,4′-dicarboxylic acid), with hydrogen-bonded–O–metal–O–chain. In additional, solid-state properties such as photoluminescence and thermal stability of the complex 1 have also been studied. [Copyright &y& Elsevier]

Through hydrothermal reactions, 4,4′-bipyridine (bpy) co-ligands firstly was introduce to CdII-H2FDC system (H2FDC=9-fluorenone-2,7-dicarboxylic acid), generating a new coordination polymer {[Cd2(FDC)2(bpy)]∙H2O}n (1). Compound 1 has a pillar-layer 2-fold interpenetrating pcu network, based on the square-grid tetranuclear [Cd4(COO)8] units. Interestingly, 1 shows a blue-shifted photoemission, as well as enhanced fluorescence lifetime compared with the pure H2FDC ligand. [ABSTRACT FROM AUTHOR]
