S-Benzyl-thio-uronium 3-nitro-benzene-sulfonate.

In the title compound, C(8)H(11)N(2)S(+)·C(6)H(4)NO(5)S(-), the asymmetric unit is composed of two crystallographically independent S-benzyl-thio-uronium cations and two independent nitro-benzene-sulfonate anions. An intra-molecular hydrogen bond generates an S(5)S(5) ring motif. The crystal packing is stabilized by intra-molecular C-H⋯O and inter-molecular C-H⋯O, N-H⋯O and N-H⋯S hydrogen bonds which, along with short S⋯O [3.034 (2) Å] and N⋯O [2.796 (3) Å] contacts, form a two-dimensional network parallel to the ab plane.
