14. Proton transfer between highly charged polyoxometalate anions in acetonitrile and similar nonaqueous solvents is frequently slow on NMR and voltammetric time scales, see, for example: Finke, R. G.; Rapko, B., Saxton, R. J.; Domaille, P. J. J. Am. Chem. Soc. 1986, 108, 1986. Harmalker, S. P.; Pope, M. T. J. Inorg. Biochem. 1986, 28, 85.
