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⋯π and π–π interactions; the latter occur between centrosymmetrically related 1,2,3-triazole rings [centroid–centroid distance = 3.6056 (14) Å].

A mixture of 5-methyl-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide (0.22 g, 0.001 M) and indoline-2,3-dione (0.15 g, 0.001 M) in anhydrous ethanol (30 ml) in the presence of a catalytic amount of glacial acetic acid was heated under reflux for about 4 h. The resultant solid was filtered and dried. Re-crystallization was by slow evaporation of its DMF solution which yielded yellow prisms in 73% yield; M.pt: 562–564 K.
Carbon-bound H-atoms were placed in calculated positions (C—H = 0.93 to 0.96 Å) and were included in the
in the riding model approximation, with Uiso(H) = 1.2–1.5Uequiv(C). Nitrogen-bond H-atoms were refined with the distance restraint N—H = 0.88±0.01 Å, and with unrestricted Uiso.Data collection: CrysAlis PRO (Agilent, 2011); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound (I) was investigated in relation to the established biological activities exhibited by 1,2,3-triazoles (Abdel-Wahab et al., 2012; Jordão et al., 2011).
With respect to the 1,2,3-triazole ring (r.m.s. deviation = 0.010 Å) in (I), Fig. 1, both the benzene [dihedral angle = 26.20 (13)°] and to a lesser extent the amide residues are twisted [C10—C7—C8—C9 torsion angle = -8.8 (4)°]. The nine non-hydrogen ring atoms of the 3-imino-1H-indol-2-one residue are co-planar, having a r.m.s. deviation of 0.032 Å. The formation of intramolecular N4—H···O2 and N4—H···N3 hydrogen bonds, Table 1, confers stability to the co-planar arrangement in the central region of the molecule, i.e. the N4—N5—C12—C11 and N3—C7—C10—N4 torsion angles are -0.9 (3) and -6.3 (3)°, respectively. Finally, the conformation about the N5═C12 bond is Z.
Supramolecular chains propagating along [1 0 1] feature in the crystal packing. These are sustained by N6—H···O1 hydrogen bonds and supported by C14—H···O2 interactions, Table 1, and lead to 12-membered {···OCN2C3H···OCNH} synthons, Fig. 2. The chains assemble in layers parallel to (1 0 1) and are connected into the three-dimensional architecture by C—H···π interactions between a methyl-H and the C13–C18 benzene ring, Table 1, and π—π interactions between centrosymmetrically related 1,2,3-triazole rings [inter-centroid distance = 3.6056 (14) Å for symmetry operation 1 - x, 1 - y, 1 - z], Fig. 3.
