ResumoThe redox behaviour of di-, tri-, penta- and hexaphospha ferrocene complexes and of five transition metal carbonyl complexes of the triphospha ferrocene [Fe(η5-C2tBu2P3-(η5-C5Me5)] 2 has been investigated by cyclic voltammetry. The oxidation potential of the phospha ferrocene complexes is determined by the number of electron-donating alkyl groups and phosphorus atoms, the latter showing electron-withdrawing properties. Electrochemical investigations on metal carbonyl complexes of 2 revealed an anodic shift of the oxidation potential of 2. The data allow conclusions to be drawn about the overall σ-donor-π-acceptor properties of 2.
