    Abstract

    The synthesis and structural analysis of the 1,2-bis(ferrocenyl)digermene (E)-Tip(Fc)Ge=Ge(Fc)Tip (Tip = 2,4,6-triisopropylphenyl, Fc = ferrocenyl), a stable crystalline compound, is reported. In this digermene, two ferrocenyl d electron systems are bridged by a Ge=Ge π spacer. As is evident from X-ray crystallographic, spectroscopic, and electrochemical analysis, this 1,2-bis(ferrocenyl)digermene shows effective d-π interaction and the Ge=Ge π bond is stable in the solid state. The Ge=Ge double bond is cleaved at elevated temperatures in the presence of butadiene, with concomitant loss of the π conjugation in the molecule.
