Synthesis, Characterization and X-Ray Structure of Bis(O-propyldithiocarbonato-κ2 S,S′)bis(4-cyanopyridine-κN)nickel(II)

Abstract

The [Ni(S2COCH2CH2CH3)2(C6H4N2)2] adduct of 4-cyanopyridine with [Ni(S2COCH2CH2CH3)2] was synthesized and characterized by elemental analysis, magnetic susceptibility measurement, IR, electronic spectral data, Thermogravimetric analysis/DTA techniques and X-ray diffraction analysis. The Ni atom in the title complex is octahedrally coordinated within a trans-N2S4 donor set, with the Ni atom located on a centre of inversion. The title complex crystallizes in the monoclinic space group P2 1 /c with unit cell parameters a = 11.75(4), b = 11.62(3), c = 9.20(2) A, β = 104.99(3)°. Crystal structure was solved by direct methods and refined by full matrix least squares procedures to a final R-value of 0.0294 for 1895 observed reflections. The packing of layers of molecules is stabilized by weak C–H···N and C–H···π interactions.
