摘　　要：以12-钨磷酸和二苯胺为原料合成了一种电荷转移盐。通过元素分析确定其组成为[（C6H5）2NH2]3[PW12O40]·4H2O，各元素的质量分数分别为（括号内为理论值）C 12．91％（13．08％），H 1．304％（1．344％），N 1．793％（1．793％），采用红外光谱、紫外．可见分光光度法、X射线粉末衍射等测试技术对该化合物进行了分析表征。结果表明：所合成的新型电荷转移化合物的杂多阴离子保持Keggin结构特征。A charge transfer salt was synthesized with 12-tungstenphosp horic acid and diphenylamine in aqueous solution. It＇s molecular formula was determined as [（C6H5）2NH2]3[PW12O40]· 4H2O by element analysis. The mass fractions of elements are （the numbers in bracket are theoretical values） C 12.91%（13.08%）, H 1.304%（1.344%）, N 1.793%（1.793%）. The compound was characterized by X-ray powder diffraction analysis, IR and UV-Vis spectrophotometry. The results indicate that it keeps the Keggin structure of anion, but the Keggin structure is more or less transformed under the influence of diphenylamine.
