Keggin结构的钨磷钒稀土四元杂多配合物的合成和物化性质

Synthesis and Properties of the Rare Earth Element Tungstovanadophosphoric Tetrabasic Heteropoly Complexes with Keggin Structure

合成了９种具有Ｋｅｇｇｉｎ结构特征的钨磷钒稀土四元杂多配合物，利用化学分析，ＩＲ．ＵＶ，ＸＰＳ，ＥＳＲ，ＴＧ－ＤＴＡ’ＸＲＤ等手段对配合物进行了表征。

Nine in one series of the rare earth element tungstovanadophosphoric tetrabasicheteropoly complexes with Keggin structtire were synthesized and characterized by chemicalanalysis, XPS,IR,UV,ESR,NMR,XRD and TG-DTA methods.
