| Summary: | In the title compound, C8H11N2S+·C12H10NO3S−, the NH group of the S-benzylthiuronium is protonated and the interplanar angle between the phenyl ring and the CH2—S=C(NH2)2 unit is 47.44 (10)°. In the 4-anilinobenzenesulfonate anion, the interplanar 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 interactions link the cations to the anions in chains along the b-axis direction. These chains are further interconnected into a two-dimensional network parallel to the bc plane by C—H...O interactions. C—H...π contacts are also observed.
