Abstract: In the title compound, C₁₉H₁₈NO₂⁺. C₇H₇SO₃^-, the cation is almost planar and the benzene ring of the anion makes dihedral angles of 59.17 (9) and 60.59 (10)° with the mean planes through the quinolinium and benzene ring of the cation, respectively. The cations and anions are packed as alternate layers along the b axis. These layers are interconnected through O-HO and C-HO interactions to form a three-dimensional network. The structure is stabilized by these interactions and C-H [pi] interactions.
