摘要：

The electron-transfer reaction between bis(cyclopentadienyl)iron(II) ([Fe-II(C5H5)(2)]) in nitrobenzene and a hexacyanoferrate redox couple ([Fe-II/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 [Fe-II/III(C5H5)(2)](0/+) and [Fe-II/III(CN)(6)](4-/3-) in the water phase have been determined. The electron-transfer reaction between [Fe-II(C5H5)(2)] in 1,2-dichloroethane and [Fe-II/III(CN)(6)](4-/3-) in water at the 1,2-dichloroethane \ water interface was shown to also take place by the IT-mechanism.
