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-HN and N-HS hydrogen bonds, forming R22(8) ring motifs. Molecules are further linked by slightly weaker N-HN, N-HS and C-HS hydrogen bonds, forming two-dimensional networks which lie parallel to the bc plane.
For standard values of bond lengths, see: Allen et al. (1987). For hydrogen-bond motifs, see: Bernstein et al. (1995). For related structures, see: Cowley et al. (2004); Lobana et al. (2011). The antitumor and antibacterial activity of thiosemicarbazones and thiosemicarbazides has been attributed to their ability to chelate trace metals, see: Kirschner et al. (1966). For the preparation of hexan-2,5-dionebis(thiosemicarbazone), see: Nandi et al. (1984).
