Crystal structure and Hirshfeld surface analysis of 4-bromo-2-chloro-phenyl (E)-3-[4-(undec-yloxy)phen-yl]acrylate.

In the title compound, C(26)H(32)BrClO(3), the dihedral angle between the 4-bromo-2-chloro-phenyl ring and the aromatic ring of (alk-yloxy)phenyl moiety is found to be 77.21†(2)°. The torsion angle associated with the ester moiety is 173.2†(2)° which is anti-periplanar. In the crystal, inter-molecular C-H⋯O hydrogen bonding links the mol-ecules into cyclic hydrogen-bonded inversion dimers with R (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 R (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 significant contributions are from H⋯H (54.0%), C⋯H/H⋯C (15.2%), Br⋯H/H⋯Br (10.9%), O⋯H/H⋯O (7.8%) and Cl⋯H/H⋯Cl (2.6%) contacts.
