(a) Cyclic voltammograms of 1^2−/1− (top, red), 2^0/1− (middle, black), and a mixture of the two clusters (bottom, blue) at 1 mM in 0.5 M TBAPF₆ in MeCN at a scan rate of 10 mV s⁻¹, referenced to ferrocene/ferrocenium at 0 V. (b) Measured electrochemical parameters for 1^2−/1− and 2^0/1− calculated at 10 mV s⁻¹. (c) EPR spectrum and calculated SOMO energy state representation of 1⁻¹.²²
