Heterogeneous electron-transfer rate constants were measured for a series of bis(ligated)iron(III) octaethylporphyrin and tetraphenylporphyrin complexes in CH2Cl2 (0.1 M TBAP).The former series of complexes exist in a spin equilibria while the latter are predominantly low spin at room temperature.Values of the magnetic moment were calculated for each complex and comparison made between this μeff and the ko and E1/2 of electron-transfer process Fe(III) ->/eff and ko and E1/2 varied as a function of ligand for the complexes of (OEP)Fe(L)2+ClO4.Contrary to expectation, however, no substantial changes were observed in ko as a function of spin state.This was true for comparisons of the (OEP)Fe(L)2+ and (TPP)Fe(L)2+ series as well as for intercomparisons between the high- and low-spin complexes of (OEP)Fe(L)2+.
