Abstract
Thin-layer electrochemistry and steady-state current-potential curves were used to study the electrochemical behavior of the {(TPA)Mn(III)(2 )Mn(IV)(TPA)}(2)(SO4)(3) complex in an aqueous medium and forecast its role in a catalytic reaction using the usual oxidants. By studying th e concentration and pH effects it is possible to assess the complex's stability domain, on the one hand, and to characterize the oxidation s tate of the two manganese atoms and construct a potential-pH diagram i ncluding the various equilibria between the manganese species on the o ther.
