Complex	E ox 1/2 (V)	E red 1/2 (V)	ΔE (V)	E HOMO  b (eV)	E LUMO  b (eV)
1	1.60	–1.36	2.96	–6.03	–3.06

^aMeasurements were carried out in MeCN at a scan rate of 100 mV s^–1 with Fc/Fc⁺ employed as an internal standard, and reported vs. SCE (Fc/Fc⁺ = 0.38 V in MeCN).²² Reported potentials are referenced to the Fc/Fc⁺ redox couple.

^b E _HOMO/LUMO = –[E ^ox/red vs. Fc/Fc⁺ + 4.8] eV.²³
