Synthesis and characterisation of some [M(C3S5)2]n− complexes (M = Ni, Pd, Pt). Single crystal structure of [PPN] [Ni(C3S5)2] · MeOH
摘要:
The synthesis and characterisation of some anionic Ni, Pd and Pt complexes of the ligand, Na2C3S5, (C3S52- = 1,3-dithiole-2-thione-4,5-dimercapto = dmit) are reported. The complexes were isolated as PPN+ [PPN+ = bis(triphenylphosphine)iminium] salts. The monoanionic complexes [PPN] [Ni(C3S5)(2)] and [PPN] [Pd(C3S5)(2)] were further oxidised with iodine in acetonitrile to afford [PPN](0.25)[Ni(C3S5)(2)] and [PPN](0.25)[Pd(C3S5)(2)]. The partially oxidised complexes have electrical conductivities of 1.2 x 10(-2) and 0.64 S cm(-1) al room temperature for compacted pellets. Cyclic voltammetry, electronic, IR and ESR spectra of the complexes are discussed. A single crystal X-ray determination of [PPN] [Ni(C3S5)(2)]. MeOH was carried out. The average value of Ni-S bond length is one of the highest observed for a [Ni(dmit)(2)] complex. (C) 1997 Elsevier Science Ltd.
