Reactions between the O/sub 2//sup -/. have been investigated in the transition-metal complexes, ..mu..-amino-..mu..-superoxo-bis(bisethylenediamine cobalt(III)) and ..mu..-superoxo-bis(pentacyano)cobalt(III). After production of the superoxide ion by pulse radiolysis of aqueous solutions, saturated with oxygen, containing 0.1M sodium formate, the reaction with the complex was followed by monitoring the formation of the peroxo complex using spectrometric pulse radiolysis techniques. Results of these studies indicate that the coordination of the superoxide with cobalt(III) has the same effect as the hydrogen ion in the superoxide dismutation reaction: 2O/sub 2//sup -/. + 2H/sup +/ ..-->.. O/sub 2/ + H/sub 2/O/sub 2/. (BLM)
