The reactions of a series of hybrid, potentially bidentate ligands Ph2P(CH2)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 [MCl2(P-SR)], cis- or trans-[MX2(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.

Abstract
The reactions of a series of hybrid, potentially bidentate ligands Ph2P(CH2)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 [MCl2(P-SR)], cis- or trans-[MX2(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.Pubblicazioni consigliate
