摘要
以粉状白钨酸为原料,在二甲基亚砜(DMSO)介质中制得了某些DMSO配位多价金属的六聚钨酸盐[M(Ⅱ)(DMSO)_6][W_6O_(19)](M(Ⅱ)=Mn,Cu,Ca,Zn,Co,Ni)和[M(Ⅲ)(DMSO)_(10)]_2·[W_6O_(19)]_3(M(Ⅲ)=Pr,Nd).测定了它们的紫外、红外光谱及电化学还原性质.
The title compounds have been successfully prepared by the reaction of the respective metallic carbonates,acetates,nitrates or sulfates with dimethyl sulfoxide solution of white powdery tungstic acid. All these compounds are hexa- or deca- DMSO coordinated hexatungstates, existed as well defined crystals,[(DMSO)6M(Ⅱ)][W6O19](M=Mn,Cu,Co,Ni,Zn,Ca)and[(DMSO)10M(Ⅱ)]2. [W6O19]3(M=Pr,Nd). The results of elemental analyses,IR and UV spectra are hereby preseted. The electro-chemical reduction behavior has also been studied.
