Abstract

Electrochemical studies of a new Mn(III)(OH) complex clearly evidence that the presence of outer spheres water molecules is essential for the reversibility of MnIII/II and MnIV/IIIredox processes. In the MnIII/II case we found an isotope effect for D2O and 18OH2 allowing us to propose a mechanism for H2O/HO− ligand exchange coupled electron transfer activation of Mn–OH2
