1-[(1-Benzyl-1H-1,2,3-triazol-4-yl)meth­yl]indoline-2,3-dione

In the title compound, C₁₈H₁₄N₄O₂, the triazole ring makes dihedral angles of 77.32 (8) and 75.56 (9)°, respectively, with the indoline residue and the terminal phenyl group. In the crystal, mol­ecules are linked by C—H...N hydrogen bonds into tapes parallel to the b axis. The tapes are linked together by π–π inter­actions between triazole rings [inter-­centroid distance = 3.4945 (9) Å].
