Synthesis, X-ray Structures, and spectroscopic characterization of cis and trans-bis(O-propyldithiocarbonato)bis(pyridine)nickel(II), cis and trans-[Ni(CH3CH2CH2OC(S)S)2(C5H5N)2]

Abstract

Single crystals of cis and trans-bis(O-propyldithiocarbonato)bis(pyridine)nickel(II), cis and trans-[Ni(CH3CH2CH2OC(S)S)2(C5H5N)2], have been prepared and studied using single crystal X-ray diffraction method and IR spectroscopy. The crystal structure of tetracoordinated Ni(II) xanthate complex, bis(O-propyldithiocarbonato)nickel(II), [Ni(CH3CH2CH2OC(S)S)2], was also determined and compared with the previously reported structure. The existence of a cis form for a hexacoordinated species of the [NiS4N2] type is infrequent for this family of complexes.
