S-Benzyl-thiouronium 4-anilinobenzene-sulfonate.

In the title compound, C(8)H(11)N(2)S(+)·C(12)H(10)NO(3)S(-), the NH group of the S-benzyl-thiuronium is protonated and the inter-planar angle between the phenyl ring and the CH(2)-S=C(NH(2))(2) unit is 47.44†(10)°. In the 4-anilinobenzene-sulfonate anion, the inter-planar angle between the two rings is 44.07†(8)°. In the crystal structure, anions are linked into chains along the c-axis direction by N-H⋯O hydrogen bonds, while additional N-H⋯O inter-actions link the cations to the anions in chains along the b-axis direction. These chains are further inter-connected into a two-dimensional network parallel to the bc plane by C-H⋯O inter-actions. C-H⋯π contacts are also observed.
