    The synthesis of the 1,1‘,3,3‘-tetrabutenyl-substituted metallocenes C5H3(CMe2CH2CHCH2)22M (M = Fe 1, Co 2, Ni 3), their electrochemical properties, and the solid-state structures of 1 and 3 are presented. Hydrosilylation of 1 with dimethylphenylsilane leads to C5H3(CMe2(CH2)3SiMe2Ph)22Fe, 4. The π-coordination ability of the arene system in 4 has allowed the preparation of the pentanuclear complex C5H3(CMe2(CH2)3SiMe2(η6-C6H5−Cr(CO)3)22Fe, 5, containing a ferrocene core and peripherial η6-coordinated Cr(CO)3 moieties. Electrochemical investigations of 5 show a reversible oxidation of the ferrocene unit as well as an independent, noninteracting irreversible oxidation of the Cr centers.
