The preparation of a number of polymeric, octahedral bis(N- alkylmonothiocarbamato)nickel(II) complexes and some of their base adducts is described. ��� The preparation and characterization of some bis(phosphine)bis(N- alkylmono-thiocarbamato)palladium(II) compounds are also described for the first time. The butyl compound is monomeric in chloroform and infrared spectral measurements of all compounds indicate that the monothiocarbamate ligands are bonded to palladium through the sulphur atoms only. The proton magnetic resonance spectrum of the dimethylphenylphosphine complex shows clearly that the phosphine groups are trans in the complexes. ��� Simple bis(monothiocarbamato)-palladium(II) or -platinum(II) have not been isolated but pyrrolidinium tetra(N- pyrrolidylmonothiocarbamato)-palladium(II) or -platinum(II) compounds are formed. Infrared measurements indicate that the mono-thiocarbamate ligands are bonded to the metal through both oxygen and sulphur atoms but no definite structure can be proposed for these compounds at present.
