Abstract

The asymmetric unit of the title compound, C 17 H 14 ClNO 2 , contains two molecules, a and b , where the hydrobenzene and pyrrole rings are in screw-boat and half-chair conformations, respectively. In the crystal, C—H...O and C—H...Cl hydrogen bonds link the molecules into two-dimensional networks, enclosing R 3 3 (19), R 2 2 (18) and R 2 2 (14) ring motifs. Hirshfeld surface analysis revealed that the most important contributions to the crystal packing are from H...H (41.4 and 41.5% for molecules a and b , respectively), H...C/C...H (18.1 and 20.2%), H...O/O...H (16.0 and 13.4%) and H...Cl/Cl...H (13.4 and 11.9%) interactions.
