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'_xH_y[GeW_9M_3(H_2O)_3O_(37)]·nH_2O(M'=Bu_4N ̄+,K ̄+;M=Cr ̄3+,Mn ̄2+,Co ̄2+,Ni ̄2+,Cu ̄2+)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。
systematic study on the redox property of tungstogermanate isomers α- and β-M_xH_y[GeW_9M_3(H_2O)_3O_(37)]·nH_2O(M'=Bu_4N ̄+,K ̄+;M=Cr ̄3+,Mn ̄2+,Co ̄2+,Ni ̄2+,Cu ̄2+)was carried out by polarography and voltammetry in aqueous solution. A redox mechanismwas proposed and the effects of substituted elements and the structure of anions on the redoxproperty were discussed.The oxidation abilities of the α-andβ-isomers were compared.
