The title compound, C21H17NO2, crystallizes with two independent molecules (AandB) in the asymmetric unit. The indoline ring system is almost planar in both molecules (r.m.s. deviations = 0.020 and 0.024 Å for moleculesAandB, respectively). The benzyl and phenol rings are inclined to the indole ring system by 80.39 (12) and 68.39 (12)° in moleculeA, and by 79.90 (13) and 74.88 (10)° in moleculeB. The aryl rings are inclined to one another by 33.30 (14) and 30.62 (14)° in moleculesAandB, respectively. In the crystal,Amolecules are linked by pairs of O—H...O hydrogen bonds, forming inversion dimers. The same situation is observed for theBmolecules and both sets of inversion dimers encloseR22(14) ring motifs. These dimers stack along thea-axis direction and are linked by offset π–π interactions [intercentroid distance = 3.6802 (13) Å] involvingAandBindole ring systems, forming layers parallel to theabplane.
