In the title compound, C8H8N4, the dihedral angle between the triazole ring [maximum deviation = 0.003 (1) Å] and the benzene ring is 34.57 (7)°. In the crystal, molecules are linked into sheets lying parallel to the ac plane via intermolecular N-HN and C-HN hydrogen bonds. Aromatic - [centroid-centroid distance = 3.6750 (8) Å] stacking and N-H interactions are also observed.
