Zero‐field ⁵⁷Fe Mössbauer spectrum of a solid sample of 1 recorded at 77 K (left). The gray circles are experimental data and the solid black line represents the numerical fit. Cyclic voltammogram of 1 (10 mM) in 4FB with [NBu₄][Al(OR^F)₄] as conducting salt (right). Measurements were done at sweep rates of 20, 50 and 100 mV s⁻¹. The half‐wave potential was found to be independent of the sweep rate.
