Organic-inorganic hybrid based on the molybdenum tellurite

Two novel organic-inorganic hybrid molybdenum tellurites [M-2(bpy)(2)][Te2MO6O24] (M=Cu(II) 1, M = Ni(II) 2; bpy = 2,2'-bipyridine) have been hydrothermally synthesized and characterized by the elemental analyses, IR spectra, TG analyses, X-ray powder diffraction and single-crystal X-ray diffraction. Compound 1 crystallizes in the triclinic system, space group P-1, with a = 7.7824(5) angstrom, b = 9.7506(6) angstrom, c = 12.4885(8) angstrom. alpha = 98.867(1)degrees, beta = 107.027(1)degrees, gamma = 102.425(1)degrees and Z = 2. Compound 2 crystallizes in the triclinic system, space group P-1, with a = 7.7928(5) angstrom, b = 9.7436(6) angstrom, c = 12.4764(8) angstrom, alpha = 98.904(1)degrees, beta = 107.211(1)degrees, gamma = 102.192(1)degrees and Z = 2. Compounds 1 and 2 are iso-structural, and both exhibit interesting 1-D ribbons bridged by metal-organic complex moieties [M (bpy)](2+) (M = Cu and Ni). Furthermore, the three-dimensional supramolecular architectures of compounds 1 and 2 are further formed by pi-pi stacking interactions of 2,2-bpy groups. (c) 2008 Elsevier B.V. All rights reserved.
