2-(2,3-Dimethyl­phen­yl)-1H-isoindole-1,3(2H)-dione

In the title compound, C(16)H(13)NO(2), 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⋯π 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.
