ABSTRACT
In the title indolin-2-one derivative, C15H11NO, the phenyl ring and the oxoindoline fused-ring system (r.m.s. deviation = 0.011 Å) are aligned at 48.52 (6)°. In the crystal, inversion-related molecules form an N—H...O hydrogen-bonded dimer via an eight-membered {...HNCO}2 synthon. The dimeric aggregates are linked into a three-dimensional architecture via C—H...O and π–π interactions between the five- and six-membered rings of the fused ring system, with an inter-centroid distance of 3.4538 (8) Å.
