We succeeded in the synthesis of an anionic stannaferrocene by the reaction of a dilithiostannole with a Fe(III) reagent, which cannot be achieved by the use of cyclopentadienyl (Cp) and its related ligands. The Mössbauer spectroscopic analysis and quantum-chemical calculations indicate that the contribution of a resonance form arising from a Fe(I) and two stannole anion is the most plausible state. The cyclic voltammetry of the anionic ferrocene revealed a quasi-reversible oxidation wave at (Epa = 11.60, Epc = 11.40, E1/2 = 11.50 V vs Fc/Fc+), lower than that of the parent ferrocenide anion, owing to the introduction of the aromatic dianionic stannole ligands.
