Abstract Some 32 novel hemin alkoxides, aryloxides, hydroxamates, sulfonates, oximates and other derivatives have been prepared and their infrared, visible and Mossbauerspectra measured. Room temperature Mossbauerspectra can be classified into four general types: A, unsymmetrical doublet with lower energy peak broadened; B, singlet (or perhaps symmetrical unresolved doublet); C, unsymmetrical doublet

required in the PINO/ferroceneselectron-transfer process. Knowing the ferrocene/ferrocenium self-exchange reorganization energy it was possible to calculate a value of 49.1 kcal mol-1 for the PINO/PINO- self-exchange reaction in CH3CN. Moreover, from the Marcus cross relation and the self-exchange rates of ferrocene and dimethylferrocene, the intrinsic reactivity of PINO in electron-transfer reactions has
