A series of homochalcogenide and mixed-chalcogenide ligand complexes of palladium and platinum have been prepared from the reactions of Pd(dppf)Cl2, (dppf = 1,1′-bis(diphenylphosphino)ferrocene), Pd(dippf)Cl2 (1,1′-bis(diisopropylphosphino)ferrocene), and Pt(dppf)Cl2 with 1,2-benzenedithiol (HSC6H4SH) (a), 3,4-toluenedithiol (HSC6H3MeSH) (b), 3,6-dichloro-1,2-benzenedithiol (HSC6H2Cl2SH) (c), 2-mercaptophenol (HSC6H4OH) (d), thiosalicylic acid (HSC6H4CO2H) (e) and thionicotinic acid (HSC6H3NCO2H) (f). Single-crystal X-ray diffraction studies show that all complexes have distorted square-planar geometry. The complexes undergo two quasi-reversible or irreversible one-electron redox processes that involve the chalcogen ligands and diphosphinoferrocene ligands. The oxidation potentials of the chalcogen ligands increase when they bear electron-withdrawing substituents.

A series of platinum(II), palladium(II) and nickel(II) complexes containing thiosalicylate ligands have been prepared by the reaction of [MX2L2] complexes [X = halide or acetate; L or L2 = ancillary neutral donor ligand such as a tertiary phosphine or cycloocta-1,5-diene (cod)] with thiosalicylic acid in methanol with added pyridine. Displacement of the cod ligand from [Pt(SC6H4CO2)(cod)] with phosphines and phosphites allows the synthesis of additional derivatives. The complexes [Pt(SC6H4CO2)(PPh3)2] and [Ni(SC6H4CO2)(dppp)] [dppp = 1,3-bis(diphenylphosphino)propane] have been the subjects of single-crystal X-ray diffraction studies. While both complexes contain the expected approximately square-planar metal co-ordination environments, the plane of the thiosalicylate ligand is inclined at an angle of 45.9° to the platinum co-ordination plane, but at only 9.4° to the nickel plane. The results of an electrospray mass spectrometry study of the thiosalicylate complexes and some related thioglycolate, 2-sulfanylpropionate and salicylate derivatives are discussed in terms of the stabilities of the complexes.
