%X In the title molecule, C13H12ClNO, the dihedral angle between the benzene and pyrrole rings is 1.38 (9)¡ã. The cycloheptene ring adopts a distorted twist chair and sofa conformation. Intermolecular N¡ªH...O hydrogen bonds form an R22(10) loop in the crystal packing. Further, weak C¡ªH...O and C¡ªH...¦Ð (involving the benzene ring) interactions are found in the crystal structure.
