Proton-coupled electron transfer in[(bpy)2Mn(O)2Mn(bpy)2]3+

In this paper we report the electrochemistry of 1 [(bpy) 2 Mn(O) 2 Mn(bpy) 2 ] 3+ (1, bpy=2,2'-bipyridyl) at edge-oriented pyrolytic graphite (EOPG) and tin-doped indium oxide. These surfaces appear to mediate proton-coupled electron transfer; it is also clear that both forms of 1 adsorb at these surfaces under certain conditions
