Abstract

An extensive series of butyronitrile-substituted ruthenium chloride complexes [RuCl_{6 - n}L_n]^z (n = 0-6; L CH ₃(CH₂)₂CN or PrCN) has been prepared and characterized spectro-electrochemically. The complete series allowed the examination of the variation in electrode potential of Ru^III/II couple and the accompanying trends in both Cl → Ru(III) and Ru(II) → PrCN charge-transfer spectra. Systematic analysis of electrochemical and spectroscopic data led to a conceptual representation of the relative frontier-orbital energies of ruthenium, chloride, and nitrile as a function of stoichiometry.
