摘 要：The synthesis and crystal structure of an polyoxometalate-based organic-inorganic complex [Cu（DMF）3（H2O）2]2[SiMo12O40]·2H2O （DMF = N, N-dimethyl formamide） is described in this article. It was characterized using elemental analysis, thermal analysis, infrared, ultraviolet, and electron spin resonance spectroscopic studies. The X-ray crystallography analysis showed that the copper centers are pentacoordinated to show the square pyramidal geometry, and the polyanion [SiMo12O40]4· which is semi-coordinated to the copper（II） centers prevents the existence of a sixth ligand. In addition, the intracationic hydrogen interaction enhanced the stability of the copper coordination cation.
