Transfer of trisbipyridine transition metal complexes across the water-dichloroethane interface

Transfer of trisbipyridine transition metal complexes [M(bpy)3]2+ (bpy = bipyridine) across the water-1,2-dichloroethane interface can be classified as a simple transfer of a divalent cation in case that the central atom M = Fe, Ni, Ru or Os, while for M = Co, Cu or Zn the charge transfer is accompanied by considerable chemical changes, such as the ligand dissociation and the solvolysis. Thermodynamic and transport parameters characterizing the transfer of [M(bpy)3]2+ ions from water to 1,2-dichloroethane have been determined from voltammetric measurements.
