Abstract: In the 5-chlorosalicylate anion of the title salt, C6H9N2+·C7H4ClO3-, an intramolecular O-HO hydrogen bond with an S(6) graph-set motif is observed and the dihedral angle between the benzene ring and the -CO2 group is 1.6 (6)°. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxylate O atoms via a pair of N-HO hydrogen bonds, forming an R22(8) ring motif. The crystal structure also features N-HO and weak C-HO interactions, resulting in a layer parallel to (10-1).
