Reactivity of ethylenebis(dithiocarbamate) and diethyldithiocarbamate ligands towards phosphine complexes of nickel(II)

Abstract

Mono- and poly-nuclear dithiocarbamate complexes of nickel(II) containing tertiary phosphines as ligands were obtained. Depending on the nature of the phosphine [PPh₃ or Ph₂PCH₂CH₂PPh₂(dppe)] and the dithiocarbamate used [dedtc = diethyldithiocarbamate or ebdtc = ethylenebis(dithiocarbamate)], square-planar [(Ph₃P)ClNi(µ-ebdtc)NiCl(PPh₃)], five-co-ordinate [Ni(ebdtc)(dppe)], and the unusual six-co-ordinate [Ni(dedtc)₂(dppe)] complexes were obtained.
