A Novel Organic—Inorganic Complex：Synthesis and Crystal Structure of [Ca（DMSO）5（H2O）]2 SiMo12O40

A novel organic-inorganic complex [Ca(DMSO)5(H2O)]2 SiMo12O40 was synthesized from CaCl2,DMSO and H4SiMo12O40·nH2O in mixed solvent of acetonitrile and water. Its structure was characterized with elemental analysis,IR and X-ray diffraction analysis.
