determined. The mechanism of reduction of the cobalt(III) centre by e−aq has been found to vary depending upon the nature of the ligands present in the complex. When an aromatic ligand is present the formation of a coordinated ligand radical is observed. This decays via intramolecular electron transfer to produce the cobalt(II) complex. The rate constants for the intramolecular electron transfer processes
