(E)-3-(1-Phenylethylidene)indolin-2-one

Abstract

In the title molecule, C16H13NO, the indoline-2-one ring system is nearly planar [maximum atomic deviation = 0.082 (2) Å] and is oriented at a dihedral angle of 66.60 (12)° with respect to the phenyl ring. In the crystal, intermolecular N—H...O hydrogen bonds link the molecules into supramolecular dimers.
