The binuclear complex (Pcts)Fe-III(O-2(2-))Fe-III (Pcts) with PctsH(2) = phthalocyaninetetrasulfonate is stable in aqueous solution for some time (similar to 1 h) before it is irreversibly converted to (Pcts)Fe-III-O-Fe-III (Pcts). The photolysis of the peroxo complex in argon-saturated water leads to the release of oxygen and the formation of Fe-II(Pcts) with phi= 5 x 10(-4) at lambda(irr) = 333 rim. It is suggested that this photoredox reaction originates from a peroxide to Fe-III LMCT state. It is populated from Pcts IL states which are initially reached by light absorption.
