Data from cyclic voltammetry and solid-state structures have been used to compare the properties of (1) with other phosphorous-based ligands as well as carbon monoxide. Data from the solid-state structures of Ru (II) complexes show that P(OCH₂)₂(OCCH₃) has a cone angle of 104. Cyclic voltammetry data reveal that the Ru(II) complexes bearing P(OCH₂)₂(OCCH₃) have more positive Ru(III/II) redox potentials than analogous complexes with the other phosphorous ligands; however, the Ru(III/II) potential for (η⁶-C₆H₆)Ru(CO)Cl₂. For the Ru(II) complexes studied herein, these data are consistent with the overall donor ability of I being less than other common phosphines (e.g., PMe₃ or PPh₃) or phosphites [e.g., P(OCH₂)₃CEt or P(OMe)₃] but greater than carbon monoxide.
