Abstract: The title compound, C₁₅H₁₆NO₂⁺·C₆H₄ClO₃S^-, is isomorphous with the 4-bromobenzenesulfonate derivative. The cation is almost planar and the benzene ring of the anion makes dihedral angles of 82.79  (1) and 76.39  (1)° with the mean planes through the benzene ring of the cation and the pyridinium ring, respectively. The cations and anions are packed as alternate layers parallel to the ac plane. These layers are interconnected through O-HO, C-HO and C-H interactions to form a three-dimensional network.
