The torsion angle associated with the ester moiety is 173.2 (2)° which is <i>anti-periplanar</i>. In the crystal, inter-molecular C-H⋯O hydrogen bonding links the mol-ecules into cyclic hydrogen-bonded inversion dimers with <i>R</i> ² ₂(10) motifs. The mol-ecular structure is associated with an inversion centre and connected through two symmetrical C-H⋯O inter-actions, forming <i>R</i> ² ₂(10) inversion dimer motif. The packing is further consolidated by C-H⋯π and C-Cl⋯π inter-actions. Hirshfeld surface analysis showed that the most significanActa crystallographica.
