The complete molecule of the compound, C6H4N8O3, is generated by a crystallographic twofold rotation axis that runs through the central ring. The flanking ring is twisted by 20.2 (1)° with respect to the central ring. One of the amino H atoms forms an intramolecular N—H⋯N hydrogen bond; adjacent molecules are linked by N—H⋯N hydrogen bonds forming a chain running along [10-2].
