Abstract
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 1.2×10−2 and 0.64 S cm−1 at room temperature for compacted pellets. Cyclic voltammetry, electronic, IR and ESR spectra of the complexes are discussed. Å 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.
