The effects of [Co III (NH 3 ) 5 L]A n compounds (LNH 3 , H 2 O, F − , Cl − , Br − , I − , CO 3 2− ; ACl − , Br − , I − , NO 3 − ; n = 1–3) on the thermal decomposition and photolysis of hydrogen peroxide (λ irr =365 nm) were studied. Complexes containing the fluoride anion are almost inactive in terms of their catalytic/photocatalytic effects, whereas those containing the iodide anion catalyse the thermal reaction effectively. The [Co(NH 3 ) 5 Cl]Cl 2 and [Co(NH 3 ) 5 Br]Br 2 complexes show significant photocatalytic effects including an autocatalytic reaction and a marked post-irradiation effect. The photocatalytic activity is explained by the photochemical reduction of the central ion and the subsequent formation of the peroxo complexes of the [Co II (NH 3 ) 5 O 2 Co II (NH 3 ) 5 ] 4+ type.
