摘要： 关于[Ln(XM11O39)2]n-类配合物合成有一些报道,但它们均未指出其中配体及所得配合物的构型,本文以α-和β2-SiW11O398-为配体,首次合成了双-(11-钨硅酸根)合镧系元素钾盐的异构体并进行了结构表征。

Abstract: The isomers of K13[Ln(α-,β2-SiW11O39)2]· xH2O(Ln=La,Ce,Pr,Nd,Sm,Gd,Er) were prepared, and characterized by elemental analysis, polarography, CV,UV,Vis,IR and 29SiNMR spectra, magnetic moments and thermal analysis. Their stabilities and relationship between the properties and structure are discussed.

Key words: Lanthanide elements, Heteropoly tungstosilicate complex, Heteroply acid isomer
