摘要

In the title mol­ecular salt, C6H10N3O+·C7H5O3−, the cation is protonated at the N atom lying between the amine and methyl substituents and the dihedral angle between the carboxyl group and its attached ring in the anion is 4.0 (2)°. The anion features an intra­molecular O—H⋯O hydrogen bond, which closes an S(6) ring. The cation and anion are linked by two N—H⋯O hydrogen bonds R22(8) motif to generate an ion pair in which the dihedral angle between the aromatic rings is 8.34 (9)°. Crystal symmetry relates two ion pairs bridged by further N—H⋯O hydrogen bonds into a tetra­meric DDAA array. The tetra­mers are linked by pairs of C—H⋯O hydrogen bonds to generate 100 chains. Hirshfeld surface and fingerprint plot analyses are presented.
