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

The asymmetric unit of the title compound, C(15)H(12)N(2)O(3), contains two almost identical mol-ecules forming an nearly C(2-)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 mol-ecules. Within such a dimer, the phthalimide units of the two mol-ecules form a dihedral angle of 1.5†(5)°.
