摘要

Four new organic-inorganic hybrid compounds based on bicapped Keggin polyoxometalate {PMo₁₂Sb₂O₄₀}: [H₂4,4鈥?bpy][PMo₁₂Sb₂O₄₀]路6H₂O (1), [Him]₂[PMo₁₂Sb₂O₄₀]路H₂O (2), [H₃(DABCO)₂][PMo₁₂Sb₂O₄₀]路2H₂O (3) and [Mn(phen)₃][PMo₁₂Sb₂O₄₀] (4) (bpy = bipyridine, im = imidazole, DABCO = 1,4-diazabicyclo[2,2,2]octane, phen = phenanthroline) have been prepared hydrothermally and characterized by IR, UV-Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), powder XRD analyses, elemental analyses, fluorescence analysis and single crystal X-ray diffraction analyses. The four compounds are new examples of hybrid compounds based on bicapped Keggin polyoxometalate {PMo₁₂Sb₂O₄₀}. Compound 1, 2 and 3 are constructed from {PMo₁₂Sb₂O₄₀} anions and different organic moieties, respectively. Compound 4 is formed by combining {PMo₁₂Sb₂O₄₀} anions and manganese coordination complexes.
