摘要
合成了一个系列的过渡元素硅钼钨多元取代多金属含氧簇合物:K4H2[M(OH2)SiMo2W9O39].nH2O (M=Mn2+,Co2+,Ni2+,Cu2+,Zn2+,Cd2+;n=21-26)。通过IR,UV,XPS,TG-DTA,XRD对其性质进行了表征。
In this paper, a serie of multicomponent substituted polyoxometalate clusters containing silicon, tungsten, molybdenum and earlier transition metal elements were synthesized. The general molecular formular was determined: K4H2Si·nH2O (M=Mn2+,Co2+,Ni2+,Cu2+,Zn2+,Cd2+;n=21-26). By means of IR, UV, XPS, TG-DTA,the properties and structural characteristics of the new tungstomolybdosilic multicomponent polyoxometalate clusters with transition elementswere investigated.
