UV-vis absorption spectroscopy and cyclic voltammetry are used to study electronic interactions in the donor/acceptor substituted disilane Fp-Si2Me4-C6H4CH=C(CN) 2 (Fp = η5- C5H5Fe(CO) 2) (1). The synthesis of 1 was achieved by a conventional chemical route, the model substances Fp-SiMe3 (2), Fp-Si2Me5 (3) and Fp-Si2 Me4C6H5 (4) were obtained by the electrolysis of Fp2 in the presence of the appropriate chlorosilane. The structure of 1, determined by X-ray diffraction, exhibits an all-trans-array of the Fe-Si-Si-Caryl fragment, a basic requirement for optimal through-bond interaction. UV-vis and CV data indicate strong intramolecular donor/acceptor interaction in 1.
