The structures for a series of Cp(PR3)2RuSiX3 {PR3 = PMe3, SiX3 = SiCl3, SiMeCl2, SiPhCl2; PR3 = PMe2Ph, SiX3 = SiCl3} complexes were determined and compared. The Ru-Si and Si-Cl distances in these complexes increased when Cl was replaced with Me or Ph groups and correlated with the observed spectroscopic properties of these complexes. The structural variations were explained by d(Ru)-σ*(Si-Cl) π-back-bonding interactions.
