Abstract: In the title salt, C6H9N2+·C7H4ClO2-, the 3-chlorobenzoate anion shows a whole-molecule 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 R22(8) and R42(8) ring motifs. The crystal structure also features a [pi]-[pi] stacking interaction between the pyridinium rings with a centroid-centroid distance of 3.8339 (9) Å.
