  名称：

  Mixed phosphathia macrocyclic chemistry: synthesis and characterisation of [M(Ph2[14]ane P2S2)]2+(M = Pd or Pt) and [RhCl2(Ph2[14]ane P2S2)]+(Ph2[14]ane P2S2= 8, 12-diphenyl-1, 5-dithia-8, 12-diphosphacyclotetradecane)

  摘要：

  The new diphosphadithia macrocycle 8,12-diphenyl-1,5-dithia-8,12-diphosphacyclotetradecane (Ph(2)[14]aneP(2)S(2)) has been prepared and the meso isomer isolated as a white solid. Upon reaction with MCl(2), (M = Pd or Pt) in the presence of TlPF6 in refluxing MeCN this isomer gave [M(Ph(2)[14]aneP(2)S(2))][PF6](2). The crystal structure of [Pt(Ph(2)[14]aneP(2)S(2))][PF6](2).MeNO(2), shows tetradentate P2S2 co-ordination at Pt-II giving a distorted square-planar geometry with Pt-P 2.247(3), 2.252(3) Angstrom and Pt-S 2.343(3), 2.341(4) Angstrom. Phosphorus-31 and Pt-195 NMR spectroscopic data confirm retention of this P2S2 co-ordination in solution. Treatment of RhCl3.3H(2)O with Ph(2)[14]aneP(2)S(2) in refluxing aqueous EtOH followed by addition of an excess of NH4PF6 gave [RhCl2(Ph(2)[14]aneP(2)S(2))]PF6 as a yellow solid. The P-31 NMR spectrum indicates that the complex exists as the-trans-dichloro isomer exclusively, and a single-crystal X-ray structure determination confirms this. The crystal structure of [RhCl2,(Ph(2)[14]aneP(2)S(2))]PF6, shows the macrocyclic donor atoms occupying the four equatorial co-ordination sites around the central Rh-III ion, Rh-P 2.286(1), 2.300(1) Angstrom, Rh-S 2.374(1), 2.377(1) Angstrom, with trans-dichloro ligands, Rh-Cl 2.347(1), 2.354(1) Angstrom, giving a distorted octahedral geometry. Cyclic voltammetry shows that the complexes [M(Ph(2)[14]aneP(2)S(2))][PF6](2) (M = Pd or Pt) and trans-[RhCl2(Ph(2)[14]aneP(2)S(2))]PF6 each exhibit an irreversible reduction at Epc values of -1.40, -1.93 and -1.06 V vs. ferrocene-ferrocenium respectively.
