摘要
以粉状白钨酸为原料,在H_2-DMSO的介质中制得了某些DMSO配位多价金属(Cu,Co,Ni,Zn,V,Pr,Nd)的十聚钨酸盐,测定了它们的红外、紫外吸收光谱、热分析及在溶液中的稳定性。
The title compounds have been successfully prepared in DMSO-H2O medium from whitepowdery tungstic acid. They are DMSO coordinated decatungstates, exist as well definedcrystals: [M(Ⅰ)(DMSO)_4 (H_2O_2)]_2 [W_(10)O_(32)] (M = Cu, Zn, Co, Ni), [(VO) (Ⅰ) (DMSO)_4(H_2O)]_2[W_(10)O_(32)] and [M(Ⅲ) (DMSO)_8]_4[W_(10)O_(32)]_3·8H_2O (M=Pr, Nd). The results ofelemental and thermal analyes, IR and UV spectra are presented. Their stabilities in solutionshave also been examined.
