Two Novel Organic-Inorganic Hybrid Compounds Constructed from Anderson-type Clusters and Transition-Metal Complexes

Two organic-inorganic hybrid compounds based on the Anderson-type clusters [TeMo6O24](6-), [(H2O)(2)Co(TeMo6O24)][(C10N2H10)(2)] center dot A 9.5H(2)O (1), [(C10N2H9)Ni(H2O)(3)](2)[TeMo6O24] center dot A 8.5H(2)O (2), have been synthesized by hydrothermal reactions and characterized by elemental analyses, IR spectra, thermal stability analyses, and single-crystal X-ray diffraction. Compound 1 displays a 1D chain structure constructed from alternating [TeMo6O24](6-)clusters and Co2+ along the a axis with two pendant ligands 4,4'-bpy (4,4'-bipyridine). Compound 2 is composed of [TeMo6O24](6-) clusters coordinated by [Ni(bpy)(H2O)(3)](2+) moieties, and a supramolecular architecture is further formed through extensive hydrogen bonds interactions. Two organic-inorganic hybrid compounds based on the Anderson-type clusters [TeMo6O24](6-)and the unit [M(4,4'-bpy)] have been synthesized under the hydrothermal conditions. Compound 1 displays a 1D chain structure constructed covalently from alternating polyoxoanions [TeMo6O24](6-) and Co2+ along the a axis with two pendant ligands 4,4'-bipyridine. Compound 2 is composed of [TeMo6O24](6-) polyoxoanion coordinated by [Ni(bpy)(H2O)(3)](2+) moieties and shows a 1D chain structure through the hydrogen bonds interactions.
