The complete molecule of the title compound, C10H8N6, is generated by crystallographic inversion symmetry; the dihedral angle between the planes of the benzene and triazole rings is 16.7 (2)°. In the crystal, inversion dimers linked by pairs of weak C—H...N hydrogen bonds generate R22(6) loops. Weak aromatic π–π stacking interactions [centroid–centroid separation = 3.809 (1) Å] are also observed.
