Fig. 3: Redox properties of the complexes.

Cyclic voltammograms of separate 1 mM acetonitrile solutions of 1 (blue), 2 (orange), 3 (green) and 4 (red) at room temperature with nBu4NPF6 as supporting electrolyte (0.1 M). An Ag wire is used as quasi reference electrode, Pt wire as the counter electrode and glassy carbon as the working electrode. All data referenced against Fc+/Fc; scan rate = 100 mV s−1.
