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.
