| Abstract: | The novel polyoxometalate, Ni(enMe)2]2Ni(enMe)2{HMoVI4MoV4VIV8O40(VVO4)}]4H2O, was synthesized and characterized by elementary analysis, IR spectra and X-ray diffraction. The compound crystallizes in monoclinic, space group C2/c with a = 26.3006(6), b = 13.6195(3), c = 19.7122(5) ? b = 105.8330(10), V = 6793.0(3) ?, Z = 4, Dc = 2.566 g/cm3, Mr = 2623.96, m = 3.507 mm-1, F(000) = 5088, R = 0.0699, wR = 0.1526 and S = 1.018. The compound consists of infinite chains of Ni(enMe)2]2Ni(enMe)2{HMoVI4MoV4VIV8O40(VVO4)}]4H2O clusters covalently linked through Ni(enMe)2] group and another isolated Ni(enMe)2]2+ cations, occupying the interchain regions and providing charge compensation. |
