Two Novel Vanadium Tellurites Covalently Bonded with Metal-Organic Complex Moieties: M(phen)V2TeO8 (M = Cu, Ni)

Two novel two-dimensional organic-inorganic hybrid vanadium tellurites M(phen)V2TeO8 (M = Cu (1), Ni (2)) have been hydrothermally synthesized and characterized by the elemental analyses, IR spectra, EPR spectrum, XPS spectra, TG analyses, and single-crystal Xray diffraction. Compound 1 crystallizes in the monoclinic system, space group P21/c, with a = 9.2193(18) (angstrom), b = 7.9853(16) (angstrom), c = 21.401(4) (angstrom), (beta)= 97.54(3) °, and Z = 4. Compound 2 crystallizes in the monoclinic system, space group P21/c, with a = 9.2163(18) (angstrom), b = 7.9897(16) (angstrom), c = 21.386(4) (angstrom), (beta)= 97.52(3) °, and Z = 4. Compounds 1 and 2 are isostructural, and both exhibit interesting two-dimensional networks with [V2TeO8] double-chain-like ribbons bridged by metal-organic complex moieties [M(phen)]2+ (M = Cu and Ni). Furthermore, the three-dimensional supramolecular architectures of compounds 1 and 2 are formed by (pi)- (pi) stacking interactions of phen groups between adjacent layers.
