Bis(thio-semicarbazide)nickel(II) bis-[2-(thio-semicarbazonometh-yl)benzene-sulfonate] dihydrate.

In the title compound, [Ni(CH(5)N(3)S)(2)](C(8)H(8)N(3)O(3)S(2))(2)·2H(2)O, the Ni(II) atom lies on a inversion centre and is four-coordinated by two N and two S atoms of two thio-semicarbazide ligands in an almost square-planar coordination. In the crystal structure, the molecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, N-H⋯O, N-H⋯S and O-H⋯O hydrogen bonds.
