Abstract: In the title compound, C₁₆H₁₉N₂⁺·C₆H₄BrO₃S^-, the cation is nearly planar, with a dihedral angle of 3.19 (15)° between the pyridinium and the dimethylaminophenyl rings, and exists in the trans configuration. In the crystal packing, the cations and anions are linked into chains parallel to the c axis. These chains are stacked along the b axis. The crystal is stabilized by weak C-HO and C-H interactions, and a - interaction is also observed with a CgCg distance of 3.5675 (19) Å.
