Abstract: In the title compound, C7H11N2+·C7H7O3S-, the cation is protonated at the N atom of the heterocyclic ring. The dimethylamino group lies close to the pyridinium ring plane with a dihedral angle between the pyridinium and the dimethylamine CNC planes of 3.82 (17)°. The N-C bond linking the dimethylamino substituent to the pyridinium ring is characteristically short [1.3360 (19) Å], suggesting some delocalization in the cation. In the crystal structure, N-H
O hydrogen bonds link individual pairs of cations and anions. The structure is further stabilized by an extensive series of C-HO hydrogen bonds, augmented by ![[pi]](/logos/entities/pi_rmgif.gif)
- [centroid-centroid distance between adjacent pyridinium rings = 3.5807 (10) Å] and C-H interactions, giving a network structure.
