The coupling of electron and proton transfers is currently under intense scrutiny. This Communication reports a new kind of proton-coupled electron transfer within a homodinuclear first-row transition-metal complex. The triply-bridged complex [Fe^III(渭-OPh)(渭₂-mpdp)Fe^II(NH₂Bn)] (1; mpdp^{2鈥?/sup> = m-phenylenedipropionate) bearing a terminal aminobenzyl ligand can be reversibly deprotonated to the anilinate complex 2 whose core [FeII(渭-OPh)(渭₂-mpdp)FeIII(NHBn)] features an inversion of the iron valences. This observation is supported by a combination of UV鈥搗isible, 1H NMR, and M枚ssbauer spectroscopic studies.}
