ethanol. Complexes of formula Ru(η-RC5H4)(S2CX)(PPh3)2, with the dithiolate ligand monodentate, are obtained when R = H, X = OC6H11; R = CH3, X = OCH3; R = H, CH3, X = CN. In the other cass studied the isolated complexes contain a bidentate SS ligand. Steric effects as well as the electronic properties of dithiolate ligands, seem to influence the choice between the two coordination modes. Reaction
