The synthesis, characterization and single-crystal structure determination of chiral compounds (η⁵-C₅R₅)Ru(PHPh₂)(PPh₃)Cl (R=H 3, R=Me 4) and prochiral Cp * Ru(PHPh₂)₂Cl (6) are described. Compound 6 has been available from reaction of PHPh₂ and several starting materials. The X-ray structure comparison between 3, 4 and 6 allowed us to compare the influence of the phosphine, Cp and Cp * ligands in these half-sandwich compounds. In addition, a structural investigation was carried out on Cp * Ru(NBD)Cl (7).
