Thiazolidinedithiocarbamate complexes of nickel with phosphorus donor ligands in the coordination sphere

Nickel(II) thiazolidinedithiocarbamate complexes of the composition [Ni(tzd tc)(2)](n), [NiX(tzdtc)(PPh3)] (X=Cl, Br, I, SCN), [Ni(tzdtc))(dppe)]Y . nH (2)O (Y = Br, I, ClO4, NO3; n = 0, 1), [Ni(tzdtc)(dppb)]ClO4. H2O and [Ni(t zdtc) (dpph)]ClO4. H2O (tz = C3H6S; dtc = S2CN-: PPh3 = triphenylphosphine; dppe = 1,2-bis(diphenylphosphino)ethane; dppb = 1,4-bis(diphenylphosphino) butane; dpph = 1,6-bis(diphenylphosphino)hexane) have been synthesized. The compounds have been characterized by elemental analyses, IR and electron s pectroscopies, thermal analysis, magnetochemical and conductivity measureme nts. A single crystal X-ray analysis of the [NiCl(tzdtc)(PPh3)]. 0.5CHCl(3) complex proved four-coordinated nickel in a distorted square-planar arrang ement with the NiS2PCl chromophore.
