Abstract The preparation and characterization of new hybrid donor-type phosphine-thioether ligands, a linear tetradentate Me2P(CH2)2S(CH2)3S(CH2)2PMe2 (dmdtn) and a didentate Me2P(CH2)2SR [R = Me (mtdmp) or Et (etdmp)], and their cobalt(III) complexes are described. The reaction of trans-[CoCl2(PY)4]C1 (py = pyridine) with dmdtn, followed by anion metathesis with NaPF6, afforded green crystals of trans(Cl

In the title compound, chloro(eta(6)-p-cymene)[1-(dimethylphosphino-P)-2-(methylthio-S)ethane]ruthenium(II) tetraphenylborate hemidichloromethane solvate, [RuCl-(C10H14)(C5H13PS)][B(C6H5)(4)].0.5CH(2)Cl(2), the hybrid Me(2)PCH(2)CH(2)SMe ligand is bidentate (kappa(2) P,S), forming a five-membered chelate ring. The complex cation has two chiral centres, i.e, on the Ru and S atoms, and the relative configuration is R*(Ru)S*(S).

determined by NMR spectroscopy. All the palladium(II) complexes prepared in this study are cis-isomers, in contrast to the analogous Me2PCH2CH2S− (dmsp) complex (trans-[Pd(dmsp)2]), which indicates that the anionic phosphine-thiolate ligand prefers the trans geometry more than the neutral phosphine-amine or -thioether ligand does.
