The crystal structure of the title compound, has been established by Patterson and Fourier methods from single-crystal photographic X-ray diffraction data, and was refined by full-matrix least-squares to R 0.09 (673 reflections). Crystals are trigonal, space group R3c, a = 22.13(1), c = 15.06(3) Å, Z = 18. The structure is the first example of a square-planar bis(dithiocarbamato) complex with different ligand substituents to adopt the cis-conformation in the solid; this imposes a marked distortion on the NiS4 molecular core and is due to strong hydrogen bonding forces between the -NH- hydrogen and sulphur atoms of adjoining molecules, the overall molecular packing being a cylindrical array down c.
