摘　　要：目的合成一种新型杂多酸盐类配合物,测定它的结构。方法通过钼酸、咪唑、吡啶、硅酸钠和醋酸锌,采用溶液法反应,利用X-射线单晶衍射结构分析、元素分析和红外光谱对该配合物进行表征。结果得到以咪唑配位的锌离子作为阳离子的一个新的"Keggin"型的多金属杂多酸盐类配合物,表征了其结构。结论制备了锌配合物[Zn(imi)4]2[SiMo12O40].(imi)2.H2O(imi=咪唑),为后续的生物活性研究打下基础。Objective To synthesize a new polyoxometallate complex and determine its structure. Methods By using solution method, the reaction of H2MoO4, imidazole, pyridine, sodium silicate and zinc acetate in aqueous solution gave rise to the product, of which structure was determined by elemental a- nalysis, IR spectra and single X-ray crystal analysis. Results The product is a new Keggin-type anion compound with coordinated zinc as cation, and its structure had been studied. Conclusion The new zinc （Ⅱ） complex EZn（imi）4]2 [SiM012O40]· （imi）2 · H2O （imi=imidazole） and its structure data will be a firm foundation for further studies on its biological activity.
