摘　　要：利用直接法合成未见文献报道的K8[ZnMg(H2O)W11O39]·15H2O,通过ICP,IR和XRD等方法对其结构进行表征,结果表明所合成的配合物具有Keggin结构.采用化学热扩渗法对合成配合物进行稀土扩渗实验,经XPS测试表明,有微量的钆渗进配合物的体相,并与组成元素存在键合作用,导电性测试结果表明,扩渗后试样的导电率提高105倍,是一种优良的固体电解质,有望成为具有实用价值的功能材料.The synthesis of K8[ZnMg（H2O）W11O39] ·15H2O is reported for the first time. ICP,TGDTA and XPS,IR and XRD are used to characterize the title complex and the results show that the complex is Keggin structure. Rare earth co-permeation is used to treat this complex and the results of XPS indicate that Gd have permeated and diffused into the body of this sample,at room temperature, is about 10s times of that of K8 [ZnMg（H2 O） W11 O39 ] · 15H2 O, which shows a promising application as conductive material.
