        M(H2O2)   adducts have been postulated as intermediates in biological and   industrial processes; however, only one observable   M(H2O2)   adduct has been reported, where M is redox-inactive zinc. Herein,   direct solution-phase detection of an M(H2O2)   adduct with a redox-active metal, cobalt(II), is described. This   CoII(H2O2)   compound is made observable by incorporating second-sphere   hydrogen-bonding interactions between bound H2O2 and   the supporting ligand, a trianionic trisulfonamido ligand.   Thermodynamics of H2O2 binding   and decay kinetics of the CoII(H2O2)   species are described, as well as the reaction of this   CoII(H2O2)   species with Group 2 cations.
