Abstract

Abstract: Nine tetrabasic tungstovanadophosphate heteropoly rare earth element complexeswith Dawson structure were synthesized.Their general molecular formulas are K₁₅H₄[Ln·(P₂W₁₆VO₆₁)₂]·xH₂O(Ln=La³⁺,Pr³⁺,Nd³⁺, Sm³⁺,Eu³⁺,Gd³⁺,Dy³⁺,Yb³⁺).Theirstructures and properties were investigated by IR,UV,NMR,ESR,XRD,TG-DTA.Theresults showed that the series of complexes have the same structure asK₁₆[Ce(P₂W₁₇O₆₁)₂]·50H₂O.At the same time, the catalytic activity of the complexes forH₂O₂-decomposition was also investigated.
