摘要： 用电化学方法研究了过渡元素三取代钨锗杂多酸盐M′xHy[GeW9M3(H2O)3O37]·nH2O(M′=Bu4N+,K+;M=Cr3+,Mn2+,Co2+,Ni2+,Cu2+)的α-,β-异构体在水溶液中的氧化还原质,提出了它们的还原机理,讨论了取代的过渡元素和杂多阴离子的结构对氧化还原性质的影响,比较了两种异构体的氧化能力。

关键词: 钨锗杂多酸盐, 过渡元素, 取代物, 氧化还原性质

Abstract: systematic study on the redox property of tungstogermanate isomers α- and β-MxHy[GeW9M3(H2O)3O37]·nH2O(M′=Bu4N+,K+;M=Cr3+,Mn2+,Co2+,Ni2+,Cu2+) was carried out by polarography and voltammetry in aqueous solution. A redox mechanism was proposed and the effects of substituted elements and the structure of anions on the redox property were discussed.The oxidation abilities of the α- and β-isomers were compared.

Key words: tungstogermanate heteropoly complex, transitiondement, substituted complex, redox property
