The chlorophenyl ring at position 7 is disordered over two positions [site occupancies 0.480\u2005(16):0.520\u2005(16)]. The dihedral angle between the two benzene rings is 63.0\u2005(4)\u00b0.

The crystal structure is further stabilized by C\u2014H...O hydrogen bonds together with two C\u2014Cl...\u03c0 (ring) interactions. The geometry was optimized by DFT using the B3LYP\/6\u201331\u2005G(d,p) level basis set. In addition, the HOMO and LUMO energies, chemical reactivity parameters and molecular electrostatic potential were calculated at the same level of theory. Hirshfeld surface analysis indicated that the most important contributions to the crystal packing are from H...H (45.6%), Cl...H\/H...Cl (23.8%), H...C\/C...H (12.6%), H...O\/O...H (8.7%) and C...Cl\/Cl...C (7.1%) interactions.
