摘要

The title compound [Cu(DMF)(3)(H2O)](2)[alpha-SiW12O40](.)3H(2)O was synthesized in mixed solvent of water and acetonitrile by reaction of alpha-H4SiW12O40 (.) nH(2)O, CuCO3 (.) Cu(OH)(2) (.) xH(2)O and DMF. The results of X-ray diffraction analysis show that the title compound generates a neutral and discrete cluster assembled from a [alpha-SiW12O40](4-) polyoxoanion and two [Cu(DMF)(3)(H2O)](2+) coordination cations. The title compound crystallizes in the monoclinic, space group C2/c, with lattice constants: a = 21.260(4), b = 16.720(3), c = 20.160(4) beta = 105.70(3)degrees, V= 6899(2) Angstrom(3), Z= 4, D-c = 3.389 Mg/m(3), F(000) = 6240, R-1 = 0.0721, wR(2) = 0.1129.
