摘　　要：A polyoxometalate-based complex [Mn(DMSO)5H2O]2SiMo12O40 has been synthe- sized and it crystallizes in triclinic, space group P with a = 11.863(2), b = 12.750(3), c = 13.255(3) , a = 83.62(3), b = 69.46(3), g = 87.14(3), V = 1865.6(6) 3, Dc = 2.445 g/cm3, Z = 1, ?= 2.660 mm-1, Mr = 2746.56, F(000) = 1328, R = 0.0569, wR = 0.1190 and GOF = 1.125. The results of X-ray crystal analysis and IR spectrum show that there exists strong interaction between the heteropolyanions [SiMo12O40]4- and coordination cations [Mn(DMSO)5H2O]2+ in solid state.
