Abstract
The reactions of a series of hybrid, potentially bidentate ligands Ph 2P(CH 2) 2SR (P-SR; R = Me, Et, Ph) with palladium(II) and platinum(II) salts are described, together with the syntheses and characterization of a variety of cationic and neutral square- planar complexes of the types [MCl 2( P- SR)], cis- or trans-[MX 2( P-SR) 2] (X = Cl, CN), [MCl( P- SR)( P- SR)] + and [M( P- SR) 2] 2+, in which the P-SR molecules can act either as chelating ( P- SR) or monodentate, P-bound ligands ( P-SR). In solution, the various species are interconverted among each other by equilibria which show a marked dependence on solvent polarity, presence of excess ligand, temperature, nature of X and R groups.
