; ; ;

The biologically important imidazole (ImH) is one of the ligands which has the potential to act as a bridging group in inner-sphere electron-transfer reactions. The reaction of the coordinated imidazole in the pentaamminecobalt(III) complex (Co(NH/sub 3/)/sub 5/(ImH)/sup 3 +/) with both the reductant solvated electron, e/sub aq//sup -/ and the oxidizing radical OH, is reported. The formation of the ligand radical intermediates and their subsequent decay is discussed. 2 tables.
