Abstract

In the title compound, C6H8NO+·C3H3O4−, the amino N atom is protonated, and one of the carboxyl groups is deprotonated to maintain the charge balance. In the crystal, classical N—H⋯O and O—H⋯O hydrogen bonds connect the ions into a two-dimensional network parallel to the ac plane. In addition, the structure is further stabilized by C—H⋯O and π–π inter­actions [centroid–centroid distance = 4.115 (2) Å].
