Abstract
An organic-inorganic hybrid polyoxometalate [Ni(phen)(H2O)3]2[Ni(H2O)5][H2W12O40] · 6H2O (phen = 1,10-phenanthroline) has been isolated and characterized by IR, UV, electrochemistry and single-crystal X-ray diffraction. X-ray crystallographic study indicates that the title compound is monoclinic, space group C2/c, with lattice constants a = 21.7672(17), b = 16.1189(12), c = 20.7949(16) Å, β = 107.8440(10)°, V = 6945.2(9) Å3, D c = 3.528 Mg m−3, F(000) = 6600, Z = 4, R 1 = 0.0372, wR 2 = 0.0845. The molecular fragment of the title compound consists of two supporting [Ni(phen)(H2O)3]2+ coordination cations, one supporting [Ni(H2O)5]2+ unit, one metatungstate polyoxoanion [H2W12O40]6− and six H2O molecules of crystallization.
