The synthesis, structure, photophysical and electrochemical properties of cyclometalated iridium complexes with ancillary cyano and isocyanide ligands are reported. The lack of solvatochromism and highly structured emission has indicated that the lowest energy excited state is triplet ligand centered with some admixture of singlet metal-to-ligand charge-transfer character.

The crystal structure, thermal properties and magnetic properties of a three-dimensional (3D) metal-organic open framework, with infinite one-dimensional (1D) Cu(II) oxide chains embedded in the structure are described. The studies indicate that the framework is a 1D antiferromagnetic system with a Neel temperature of 51 K and a paramagnetic impurity dominates the susceptibility below 14 K, implying the synthesized compound to be highly pure.

Research has been conducted on the iron(III) phosphates. The synthesis of these compounds has been performed from the dehydration of the hydrothermally prepared monolclinic and orthorhombic hydrated phosphates and the hydrates' structure has been determined from the crystal data.

Redertermination of the structures of both hydrates from single crystal data; Finding that the orthorhombic ion phosphate is more active than the monoclinic phase.

This paper reports the synthesis, characterization, and application of two cationic bismuthate clusters by anion templating. The compounds were synthesized under mild hydrothermal treatment and characterized by powder and single-crystal X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. The first material consists of a cationic hexanuclear bismuthate cluster octahedral in geometry and linked by 1,2-ethanedisulfonate molecules. This structure is thermally stable to about 235 °C. In the second compound, discrete cationic nonanuclear bismuthate clusters interact electrostatically with trifluoromethanesulfonate anions to pack into a nearly layered assembly. The material undergoes a transformation to Bi2O3 upon loss of the triflate groups at about 385 °C. Both materials demonstrate the use of sulfonate groups for the anion-directed assembly of these rare cationic inorganic structures. The application of the 3D octahedral bismuth cluster material toward acidic heterogeneous catalysis is also reported. [ABSTRACT FROM AUTHOR]

[Nb(η 6 -C 6 H 3 Me 3 ) 2 ] reacts with ethylenediamine (en) solutions of K 4 Ge 9 in the presence of 18-crown-6 to give [(η 6 -C 6 H 3 Me 3 )NbHGe 6 ] 2- ( 1 ) and [(η 6 -C 6 H 3 Me 3 )NbGe 6 Nb(η 6 -C 6 H 3 Me 3 )] 2- ( 2 ) as their corresponding [K(18-crown-6)] + salts. The crystalline solids are dark brown, air-sensitive, and sparingly soluble or insoluble in most solvents. The [K(18-crown-6)] + salts of cluster ions 1 and 2 have been characterized by energy-dispersive X-ray (EDX) analysis, NMR studies, single-crystal X-ray diffraction, and electrospray ionization time-of-flight (ESI-TOF) mass spectrometry studies. Cluster ions 1 and 2 have markedly different [Ge 6 ] moieties: an electron-deficient carborane-like subunit in 1 and a two-center, two-electron cyclohexane-like subunit in 2 .

Transition-metal thiophosphates and selenophosphates are layered systems with the potential for displaying two-dimensional (2D) magnetic phenomena. We present the crystal structures and magnetic properties of two lithium transition-metal thiophosphates, Li 1.56 Co 0.71 P 2 S 6 and Li 2.26 Fe 0.94 P 2 S 6 . The previously unreported Li 1.56 Co 0.71 P 2 S 6 crystallizes in the trigonal space group P 31 m with lattice parameters a = 6.0193(6) Å and c = 6.5675(9) Å. The CoS 6 octahedra are arranged in a honeycomb lattice and form 2D layers separated by lithium cations. The previously solved Li 2.26 Fe 0.94 P 2 S 6 is isostructural to Li 1.56 Co 0.71 P 2 S 6 but displays site mixing between the Li + and Fe 2+ cations within the thiophosphate layer. Unusually, Li 1.56 Co 0.71 P 2 S 6 appears to have P 2 S 6 3- and not P 2 S 6 4- anions. We therefore term it a "noninnocent" anion because of the ambiguous nature of its oxidation state. Combined neutron diffraction and magnetization measurements reveal that both Li 1.56 Co 0.71 P 2 S 6 and Li 2.26 Fe 0.94 P 2 S 6 display magnetic anisotropy as well as no long-range magnetic order down to 5 K. In the iron thiophosphate, susceptibility indicates an effective moment of 5.44(3) μ B , which may be best described by an S + L model, where S = 2 and L = 2, or close to the free ion limit. In the cobalt thiophosphate, we found the effective moment to be 4.35(2) μ B , which would point to an S = 3 / 2 and L = 1 model due to octahedral crystal-field splitting.
