Abstract
In the title compound, C16H13NO2, the 2,3-dimethylphenyl group and the 1H-isoindole-1,3(2H)-dione group are essentially planar, with r.m.s. deviations of 0.006 and 0.013 Å, respectively, and are oriented at an angle of 78.19 (3) with respect to each other. In the crystal, weak C—H O interactions link the molecules, forming a zigzag chain parallel to the b axis. Futhermore, C—H interactions are present between the C—H group of isoindole and the 2,3-dimethylphenyl benzene ring. The H atoms of the ortho-methyl group are statistically disordered over two positions. Such disorder might be related to the antagonism between intramolecular steric repulsions and intermolecular C—H O interactions.
