title: Hydrothermal synthesis of a three-dimensional organic-inorganic hybrid network formed by poly(oxomolybdophosphate) anions and nickel coordination cations.
abstract: A novel organic-inorganic hybrid nickel molybdenum(V) phosphate has been synthesized hydrothermally and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and magnetic susceptibility. The structure consists of poly(oxomolybdophosphate) anions linked by both Ni(II) cations and 4,4-bipyridine bridging ligands to form a three-dimensional open-framework structure with large cavities where the uncoordinated 4,4'-bipyridinium cations and lattice water molecules are located. This is the first example of an extended framework solid containing poly(oxomolybdophosphate) anions interconnected by both transition-metal complexes and organic moieties. Crystal data: (4,4'-H2bpy)[Ni(4,4'-bpy)(H2O)2Ni(0.5)Mo6(OH)3O12(HPO4)4].2H2O, orthorhombic, space group Pccn (No. 56), a = 27.745(2) A, b = 16.158(1) A, c = 22.819(2) A, V =10230.3(1) A(3), and Z = 8.
