  • Abstract

    A series of six coordinated Ni(II)complexes with general formula [Ni(C5H4NCl) 2 (S2COC3H7)2] was synthesized and characterized. All the complexes have 1:2 stoichiometry, are non ionic and paramagnetic in nature. TGA-DTA studies show the formation of NiS as the stable end product of the decomposition. One of the adducts bis(O-propyldithiocarbonato)bis (3-chloropyridine) nickel(II) crystallizes in the monoclinic space group P21/c. The Ni2+ ion is in an octahedral coordination environment formed by an N2S4 donor set, defined by two chelating dithiocarbonate anions as well as two 3-chloropyridine ligands with the Ni2+ ion located at the inversion centre. The packing of layers of molecules is stabilized by weak π - π and C-Hπ interactions. The asymmetric unit comprises of half molecule and Nickel(II) cation lies on an inversion centre
