Abstract: In the title compound, C₁₂H₁₂NS⁺·C₆H₄ClO₃S^-, the cation is almost planar and exists in the E configuration. The cations and anions form alternate layers parallel to the ab plane. Within each layer, both cations and anions form chains directed along the b axis. The molecules are interconnected by weak C-HO interactions into a three-dimensional network. The crystal structure is further stabilized by C-H interactions involving the thiophene ring. The sulfonate and thiophene groups are involved in weak intramolecular C-HO and C-HS interactions, respectively. The latter intramolecular hydrogen bonds produce S(5) ring motifs.
