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

The asymmetric unit of the title compound, [Ni(C15H11N4OS)(2)] center dot C3H7NO, 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 center dot center dot center dot S hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked through intermolecular N-H center dot center dot center dot S, NH center dot center dot center dot O, C-H center dot center dot center dot N, C-H center dot center dot center dot O and C-H center dot center dot center dot S hydrogen bonds into infinite two-dimensional network parallel to the ab plane. The structure is further stablized by weak C-H center dot center dot center dot S interactions. The dimethylformamide solvent molecule is disordered over two sets of sites in a 0.514 (15): 0.486 (15) ratio.
