Synthesis and structure of 4-bromo-2-chlorophenyl 4′-methoxy-[1,1′-biphenyl]-4-carboxylate featuring short halogen...oxygen contacts

In the title compound, C₂₀H₁₄BrClO₃, the dihedral angles between the aromatic ring of the 4-bromo-2-chloro-phenyl and the immediate neighbour and second aromatic ring of the biphenyl moiety are 80.59 (2) and 75.42 (2)°, respectively. The dihedral angle between the rings within the biphenyl moiety is 24.57 (4)°. The torsion angle associated with the ester group linking the biphenyl ring and the 4-bromo-2-chloro-phenyl group is -166.6 (2)°. The extended structure features short halogen⋯oxygen contacts [Cl⋯O = 2.991 (3), Br⋯O = 3.139 (2) Å], forming mol-ecular sheets lying parallel to (101). The Hirshfeld surface analysis reveals that the major contributions to the inter-molecular inter-actions are from C⋯H/H⋯C (32.2%), H⋯H/H⋯H (26.3%), Br⋯H/H⋯Br (10.7%), O⋯H/H⋯O (10.4%) and Cl⋯H/H⋯Cl (7.5%) contacts.
