studied by X‐ray analysis. Complexes 1+ and 2+ displayed two anodic redox waves, whilst three well‐separated redox couples were observed for compound 3+. A combined experimental and computational study suggested that the ferrocene unit on the Fcdpb moiety in compounds 1+ and 3+ was oxidized first. In contrast, the order of the oxidation of ruthenium and ferrocene in complex 2+ was reversed. Metal‐to
