A stable peroxo- and hydroxido-bridged dinuclear cobalt(III) ethylenediammine 2,4-dinitrophenolate complex

Abstract A simple synthesis of a stable (μ-peroxo)(μ-hydroxido)bis[bis(ethylenediammine)cobalt(III)]2,4-dinitrophenolate trihydrate a dinuclear complex having peroxo-unit, Co 3 + ions along with 2,4-dinitrophenolate anion which is generated by reactions of Co 2 + with air is described. The Co 3 + complex interacts with catechol under mild acid conditions.
