Crystal structure of bis(N-methyldithiocarbamato)nickel(II)

Abstract

The crystal and molecular structure of the title compound has been determined by single-crystal X-ray diffraction methods, by conventional Patterson and Fourier heavy-atom techniques followed by block-diagonal least squares refinement to R 0·12 for 671 independent visually estimated observed reflections. Crystals are monoclinic space group P2₁/a, a= 12·20 ± 0·03, b= 9·37 ± 0·03, c= 4·20 ± 0·02 Å, β= 93·4 ± 0·2°, and Z= 2. The nickel atom occupies the special position with symmetry and is planar co-ordinated by four sulphur atoms [Ni–S 2·203(9) and 2·196(9)Å; S(1)-Ni–S(2) 79·2(2)°]. The remainder of the ligand exhibits conjugation throughout the planar NiS₂CNC system, the dimensions being as expected: C–S 1·70(1) and 1·72(1)Å, S–C–S 109·8(7); C–N 1·30(1), N–C 1·47(2)Å.
