2-[(1-Methyl-1H-pyrrol-2-yl)carbonyl-meth-yl]isoindoline-1,3-dione.

The asymmetric unit of the title compound, C15H12N2O3, contains two almost identical molecules forming an nearly C2-symmetric dimeric pattern. The dihedral angles between the pyrrole ring and the phthalimide unit are 82.95 (8) and 86.57 (8)° for the two molecules. Within such a dimer, the phthalimide units of the two molecules form a dihedral angle of 1.5 (5)°.
