Abstract: In the crystal structure of the title proton-transfer compound, CH₆N₃O⁺·C₇H₄NO₄^-, O-HO and N-HO hydrogen bonds are formed respectively between the cations and the anions, each component affording a supramolecular chain along the c axis. The cation and anion chains are further linked by N-HO and N-HN hydrogen bonds. A - interaction is also observed between the pyridine rings; the interplanar separation and the centroid-centroid distance are 3.3425 (6) and 4.6256 (11) Å, respectively.
