摘要：

The synthesis and crystal structure of an polyoxometalate-based organic-inorganic complex [Cu(DMF)(3)(H2O)(2)](2)[SiMO12O40]center dot 2H(2)O (DNIF = 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 polyarrion [SiMO12O40](4-) which is serni-coordinated to the copper(H) centers prevents the existence of a sixth ligand. In addition, the intracationic hydrogen interaction enhanced the stability of the copper coordination cation.
