摘要：

By a reaction of [NBun4]3[PMo(VI)12O40] with PPh3 in acetonitrile, two- and four-electron reduced compounds, [NBun4]3[PMo(VI)12-2nMo(V)2nO40-n] (n = 1 and 2), were isolated and characterized by means of X-ray diffractometry, FT-IR, electronic absorption, P-31 NMR and X-ray photoelectron spectroscopies. The bridging oxygen atom in a Mo(VI)-O-Mo(VI) skeleton is eliminated upon the reduction, affording two Mo(V) ions in the polyanion moiety, where the anion structure of the Keggin type is essentially retained during the reduction. An exchange reaction between [PMo(VI)10Mo(V)2O39]3-and [PMo(VI)8Mo(V)4O38]3- via a bridging oxygen atom occurs in solution within the NMR time scale.
