Organic–inorganic hybrid based on the molybdenum tellurite

Two novel organic–inorganic hybrid molybdenum tellurites [M2(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) Å, b = 9.7506(6) Å, c = 12.4885(8) Å, α = 98.867(1)°, β = 107.027(1)°, γ = 102.425(1)° and Z = 2. Compound 2 crystallizes in the triclinic system, space group P-1, with a = 7.7928(5) Å, b = 9.7436(6) Å, c = 12.4764(8) Å, α = 98.904(1)°, β = 107.211(1)°, γ = 102.192(1)° 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 π–π stacking interactions of 2,2-bpy groups.
