摘要
首次合成了具有K egg in结构的取代型硒磷钨杂多阴离子[SePW11O40]5-的三种稀土盐LnH2[SePW11O40].nH2O(Ln=L a、C e、N d),并利用元素分析、IR、UV、CV、TG-DTA进行了性质研究。结果表明,稀土离子处于杂多阴离子[SePW11O40]5-的外界,[SePW11O40]5-仍保持着K egg in型结构。
In this paper, three heteropoly tungstophosphateselenium complexes with lanthanide, LnH2[SePW11O40] · nH2O （Ln = La,Ce,Nd）, were first synthesized and characterized by elemental analyses, IR, UV, and TG-DTA. Their redox properties were also studied by means thanide cations are not in the inner sphere and heteropoly of cyclic voltammetry. All the results show that the lan anion [SePW11O40]^5- has the distorted Keggin structure.
