Trends in the UV/Vis absorption spectra indicate strong electronic coupling within the Rp-Si-Si-Caryl fragment and, therefore, closely resemble the ones observed for the corresponding iron complexes. The four compounds however, were shown to be less sensitive towards UV irradiation. The crystal structure of Rp-Si2Me4-C6H4CH=C(CN)2 was determined by X-ray diffraction and exhibits an all-trans-array of the Ru-Si-Si-Caryl moiety, what is a basic requirement for optimal through-bond interaction.
