5-Methyl-N′-[(3Z)-2-oxo-2,3-dihydro-1H-indol-3-yl­idene]-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide

In the title compound, C(18)H(14)N(6)O(2), 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⋯π and π–π inter­actions; the latter occur between centrosymmetrically related 1,2,3-triazole rings [centroid–centroid distance = 3.6056 (14) Å].
