Mixed-valence tri-..mu..-oxo iron acetates, (Fe/sup III//sub 2/Fe/sup II/O(OOCCH/sub 3/)/sub 6/L/sub 3/), L = H/sub 2/O or pyridine, are considered from the standpoint of their intramolecular electron transfer rates. Data from Moessbauer and infrared spectra and solution redox chemistry indicate that these complexes are in the Robin and Day class II, but with appreciable electron delocalization. Adiabatic potential energy surfaces are calculated for the three-center mixed-valence case and fitted to the physical data available for the mixed-valence iron trimers.
