摘要：

The formation of a yellow 12-molybdopyrophosphate complex was ascertained in both solid and solution states. A Raman spectroscopic study revealed the spontaneous transformation of the parent 18-molybdopyrophosphate anion, [(P2O7)Mo18O54](4-), via the 15-molybdopyrophosphate anion, [H-6(P2O7)Mo15O48](4-), into the 12-molybdopyrophosphate anion, [H-12(P2O7)Mo12O42](4-) in the CH3CN-water system. In contrast, 12-molybdopyrophosphate was the only heteropoly species formed in aqueous solution. It turned out that the spectrophotometric determination of pyrophosphate with the Fiske-Subbarow reagent and the Rucena-Conde and Prat reagent was based on the formation of the mixed-valence blue species of 12-molybdopyrophosphate.
