[Hexane-2,5-dione bis­(thio­semi­carba­zon­ato)]nickel(II)

In the title compound, [Ni(C(8)H(14)N(6)S(2))], the Ni(II) ion is coordinated by N(2)S(2) 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 R (2) (2)(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.
