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

In the title compound, C15H11NO3, the dihedral angle between the methoxybenzene and isoindole ring systems is 70.21 (3)°. The methoxy C atom is close to being coplanar with its attached ring [deviation = 0.133 (2) Å] and is oriented away from the isoindole moiety. In the crystal, inversion dimers linked by pairs of C—H...O hydrogen bonds generate R22(10) loops. Further C—H...O interactions lead to (010) infinite sheets and weak aromatic π–π stacking [centroid–centroid separations = 3.6990 (10) and 3.7217 (10) Å] is also observed
