摘　　要：报道了含过渡元素三元杂多配合物的合成,经ICP和TG曲线确定其化学式为K7[CrZ(H2O)W11O39].XH2O(Z=Cu2+、Mn2+、Cd2+)。通过IR、UV、XRD、XPS、TG-DTA等方法对配合物进行了结构鉴定,确定所合成的配合物为Keggin结构,并对其热稳定性进行了研究,确定所合成配合物的热分解温度范围为400~450℃。The synthesis of ternary heteropolytungstate complexes containing transition element is reported in this paper. Formula of the complex is described as K_7[CrZ(H_2O) W_(11)O_(39)]XH_2O(Z=Cu^(2+)Mn^(2+)Cd^(2+)),which is determined by TCP and TG curve. Its structure is characterized by IR,UV,XRD,XPS,TG-DTA methods,which confirmed the complex is Keggin structure.The thermolysis temperature range of the obtained complexes is 400450.
