Abstract: In the title molecular salt, C5H8N3+·C3H3O4-, the cation is essentially planar, with a maximum deviation of 0.005 (1) Å for all non-H atoms. In the anion, an intramolecular O-HO hydrogen bond generates an S(6) ring. In the crystal, the cations and anions are connected via N-HO hydrogen bonds and a weak C-HO interaction, forming layers parallel to the ab plane.
