In the title compound, [Ni(C8H14N6S2)], the NiII ion is coordinated by N2S2 donor atoms of the tetradentate thio­semicarbazone ligand, and has a slightly distorted square-planar geometry. In the crystal, inversion-related mol­ecules are linked via pairs of N—H⋯N and N—H⋯S hydrogen bonds, forming R22(8) ring motifs. Mol­ecules are further linked by slightly weaker N—H⋯N, N—H⋯S and C—H⋯S hydrogen bonds, forming two-dimensional networks which lie parallel to the bc plane.

Comment top

The antitumor and antibacterial of thiosemicarbazones and thiosemicarbazides have been attributed to their ability to chelate trace metals (Kirschner et al. 1966). Thiosemicarbazonato complexes are usually synthesized by the conventional approach of simply mixing alcoholic solutions of thiosemicarbazones and stoichiometric amounts of transition metal salt.

The asymmetric unit of the title compound, Fig. 1, comprises a thiosemicarbazone nickel(II) complex in which the NiII ion is coordinated by N2S2 donor atoms with a slightly distorted square-planar geometry. The angle between the mean planes S1–Ni1–N1 and S2–Ni1–N4 is 7.90 (4)°. The mean deviation of atom Ni1 from the mean plane N1–S1–S2–N4 is 0.0861 (5) Å. The bond lengths (Allen et al., 1987) and angles are within the normal ranges and are comparable to those reported for related structures (Cowley et al. (2004); Lobana et al. (2011).

Pairs of intermolecular N—H···N and N—H···S hydrogen bonds make R22(8) ring motifs (Bernstein et al., 1995) [Table 1].

In the crystal, molecules are linked by N—H···N, N—H···S, and C—H···S interactions forming two-dimensional networks which lie parallel to the bc plane (Table 1 and Fig. 2).

For the preparation of hexan-2,5-dionebis(thiosemicarbazone), see: Nandi et al. (1984).

Experimental top

Hexan-2,5-dionebis(thiosemicarbazone) was prepared by a method similar to that described by (Nandi et al. 1984). Hexan-2,5-dionebis(thiosemicarbazone) (1 mmol, 0.260 g) and nickel(II) acetate (0.66 g, 2.66 mmol) were placed in the main arm of a branched tube. Methanol was carefully added to fill the arms. The tube was sealed and immersed in an oil bath at 333 K while the branched arm was kept at ambient temperature. After 5 days, dark-red crystals (M.p. = 468 K) were isolated in the cooler arm and filtered off, washed with acetone and ether and dried in air (0.192 g; Yield 74%).

Refinement top

The N-bound H atoms were located in a difference Fourier map and constrained to refine on their parent atoms with Uiso(H) = 1.2Ueq(N). The C-bound H-atoms were included in calculated positions and treated as riding atoms: C—H = 0.93, 0.96 and 0.97 Å for CH, CH3 and CH2 H-atoms, respectively, with Uiso(H) = k × Ueq(C), where k = 1.5 for CH3 H-atoms, and = 1.2 for other H atoms.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
