摘要： Na2WO4-醋酐-DMF-HCl体系在光照条件下加热回流,加入溴化四丁基铵,经重结晶后分离得到蓝色晶体,通过元素分析、红外和紫外光谱、循环伏安、顺磁共振及单晶衍射等方法进行表征,结果表明:这是一个1-电子还原的以ClO4四面体为中心的α-Dawson型杂多蓝化合物。

Abstract: The title compound has been prepared by dissolving Na2WO4·2H2O in acetic anhydride-DMF-HCl.The blue crystals were obtained upon adding tetrabutylammonium bromide and being recrystallized from DMSO. The results of elementary analysis,IR,CV,ESR,UV-Vis,and single crystal X-ray diffraction indicate that the title compound is aα-Dawson type,one electron reduced "heteropoly-blue" with a central distorted ClO4tetrahedron.
