| Abstract: | Directed Synthesis of Sulfinato-O and -S Complexes of Some Transition Metals. XII Mono- and binuclear Sulfinato-S Complexes of Palladium(II) According to equations (1–7) the preparation of new mono- and binuclear sulfinato complexes of palladium(II) of the type Na[PdCl(S(O)2R)2(OH2)], (RS(O)2)2PdLn (R = C6H5, p-CH3C6H4; n = 2: L = H2O, py, PPh3; n = 1: L = bpy, phen, en) and [AsPh4]2[(RS(O)2)2+n Pd2Cl4—n] (n = 0, 2) is reported. While the pyridine compounds are trans-configurated, all the other mononuclear complexes have cis-configuration. In the binuclear complexes the bridging ligands are chlorine, [AsPh4]2[PhS(O)2)2Pd2Cl4]on the basis of the IR spectra has a center of symmetry. The anionic tetra(organosulfinato-S)palladate(II) complexes [AsPh4]2[Pd(S(O)2R)4] could be obtained for the first time by reaction of [AsPh4]2[PdCl4] with silver sulfinates according to equation (10). In all compounds, the IR and electronic spectra of which are discussed in detail, the RSO2? ligand is coordinated to palladium via sulphur. |
