Electron-transfer reactions of manganese(II) and -(III) polyamino carboxylate complexes in aqueous media

The kinetics of electron-transfer reactions involving the manganese(II) and -(III) complexes of ethylenediaminetetraacetate (edta4-) and trans-1,2-cyclohexanediaminetetraacetate (cdta4-) have been investigated in aqueous media. The cross-reactants employed in this study are osmium and cobalt tris(polypyridine) complexes, IrCl62-, and nickel polyaza complexes. The cross-reaction kinetic data have been correlated in terms of the Marcus relationship for outer-sphere electron-transfer reactions, and a self-exchange rate constant of 0.7 ± 0.4 M-1 s-1 was derived for the Mn(edta)(OH2)2-/- and Mn(cdta)(OH2)2-/- couples at 25°C. Deviations from this correlation were observed for the metal tris(polypyridine) complexes (reduced rate constants attributed to poor orbital overlap and hydrophobic/hydrophilic repulsions) and for a nickel(II) dioxime species, Ni(Hdiox)+ (enhanced reactivity related to a hydrogen-bonded precursor). The self-exchange rate constant is discussed in terms of the inner-sphere reorganization barriers to the exchange of an antibonding dσ* electron.
