Abstract

<p>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 (<i>E</i><sub>pa</sub> = −1.60, <i>E</i><sub>pc</sub> = −1.40, <i>E</i><sub>1/2</sub> = −1.50 V vs Fc/Fc<sup>+</sup>), lower than that of the parent ferrocenide anion, owing to the introduction of the aromatic dianionic stannole ligands.</p>
