Influence of the nature of the lower free orbital of platinum(IV) bipyridyl complexes on the kinetics and the mechanism of electron transfer processes in which they participate

The kinetics of outer-sphere electron transfer reactions with the participation of PtEn_xbipy_2–xCl₂]²⁺ complexes (x = 0–2) have been studied. The formal potential and the internal barrier of self-exchange reactions with the electron Pt(IV) Pt(III) have been estimated. A correlation has been shown to exist between the parameters of outer-sphere and intramolecular electron transfer.A. I. Gertsen Russian Fedagogical University, Leningrad.
