Abstract: In the title compound, C₉H₁₀N₄O₂, the pyridine ring is twisted by 16.5 (1)° from the mean plane defined by the remaining non-H atoms. An intramolecular N-HN interaction is present. In the crystal, intermolecular O-HN and N-HO hydrogen bonds link molecules into layers parallel to the bc plane. The crystal packing exhibits - interactions indicated by the short distance of 3.649 (1) Å between the centroids of the pyridine rings of neighbouring molecules.
