electrochemistry. The reduction potential of these derivatives is less affected by the nature of the ligand L than in the case of [CO(CO)3L]2. The electrochemical reduction of the tin complexes [Co(CO)4]n[Fe(CO)2Cp]3−nSnCl (n = 1–3) showed that the formation of the radical anion occurred with tin-cobalt rather than tin-chloride bond rupture. Electrolysis of these tin derivatives did not give any distannane containing
