Bis[2-(2-oxoindolin-3-yl­idene)-N-phenylhydrazinecarbothio­amidato-κ(3) O,N (2),S]nickel(II) dimethyl­formamide monosolvate

The asymmetric unit of the title compound, [Ni(C(15)H(11)N(4)OS)(2)]·C(3)H(7)NO, contains one Ni(II) complex mol­ecule and one disordered dimethyl­formamide solvent mol­ecule. The Ni(II) ion is six-coordinated in a distorted octa­hedral geometry by two N, two O and two S atoms. An intra­molecular C—H⋯S hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are linked through inter­molecular N—H⋯S, N—H⋯O, C—H⋯N, C—H⋯O and C—H⋯S hydrogen bonds into infinite two-dimensional network parallel to the ab plane. The structure is further stablized by weak C—H⋯π inter­actions. The dimethylformamide solvent molecule is disordered over two sets of sites in a 0.514 (15):0.486 (15) ratio.
