Description
The photoreduction process of [(HAMP)2Mo5O15]2- ({(AMP)2Mo5}) in aqueous solution is investigated by measurement of 31P NMR spectra of photolytes. UV irradiation led to the liberation of AMP from {(AMP)2Mo5} accompanying the reduction of molybdates and AMP hydrolysis proceeded catalytically to yield phosphate ion and the two-electron reduced species α-[PMo12O40]5- (α-PMo12(II)). The formation of α-PMo12(II) resulted from the reaction between phosphate ion and reduced molybdates, which originated from the decomposition of {(AMP)2Mo5}. Further photoreduction in this system proceeded to yield the four reduced species β-[H4PMo12O40]3- (β-PMo12(IV)). Based on these results, the photochemical degradation process of {(AMP)2Mo5} through the formation of two electron reduced [Mo14O46]10- (Mo14(II)) and disproportionation of Mo14(II) is proposed.
