Studies on White Powdery Tungstic Acid (XVI)——Preparation and Properties of Dimethyl Sulfoxide Coordinated Muttivalent Metal Hexatungstates

Abstract

Abstract: 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- DMSOcoordinated 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,IRand UVspectra are hereby preseted.The electro-chemical reduction behavior has also been studied.

Key words: White powdery tungstic acid, Dimethyl sulfoxide coordinated compound, Hexatungstate, Preparation
