title: 2-Amino-6-methyl-pyridinium 3-chloro-benzoate.
abstract: In the title salt, C6H9N2(+)·C7H4ClO2(-), the 3-chloro-benzoate anion shows a whole-mol-ecule disorder over two positions with a refined occupancy ratio of 0.505 (4):0.495 (4). In the crystal, the cations and anions are linked via N-H⋯O hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R2(2)(8) and R4(2)(8) ring motifs. The crystal structure also features a π-π stacking inter-action between the pyridinium rings with a centroid-centroid distance of 3.8339 (9) Å.
