Abstract: In the title compound, C18H14N6O2, the benzene ring is slightly twisted out of the plane of the 1,2,3-triazole ring (r.m.s. deviation = 0.010 Å), forming a dihedral angle of 6.20 (13)°. The nine non-H ring atoms of the fused five- and six-membered ring system are almost coplanar (r.m.s. deviation = 0.032 Å). The near coplanarity in the central residue is consolidated by an intramolecular bifurcated N-H...(O,N) hydrogen bond. The conformation about the N=C bond is Z. In the crystal, supramolecular chains along [101] are sustained by N-H...O hydrogen bonds and C-H...O interactions. These are consolidated into a three-dimensional architecture by C-H...[pi] and [pi]-[pi] interactions; the latter occur between centrosymmetrically related 1,2,3-triazole rings [centroid-centroid distance = 3.6056 (14) Å].
