The electron-transfer reaction between bis(cyclopentadienyl)iron(II) ([FeII(C5H5)2]) in nitrobenzene and a hexacyanoferrate redox couple ([FeII/III(CN)6]-4/3-) in water at the nitrobenzene | water interface was studied using normal pulse voltammetry. The voltammetric results indicate that the electron-transfer reaction takes place by way of a so-called ion-transfer (IT) mechanism, of which the forward and backward rate constants of the homogeneous electron-transfer reaction between [FeII/III(C5H5)2]0/+ and [FeII/III(CN)6]4-/3- in the water phase have been determined. The electron-transfer reaction between [FeII(C5H5)2] in 1,2-dichloroethane and [FeII/III(CN)6]4-/3- in water at the 1,2-dichloroethane | water interface was shown to also take place by the IT-mechanism.
