چکیده
The title compound, C(23)H(19)BrO(2), was synthesized from 13-bromo-4-hy-droxy[2.2]paracyclo-phane and benzoyl chloride. The hy-droxy and carbonyl groups are involved in intra-molecular O-H⋯O hydrogen bonding. The crystal packing exhibits weak C-H⋯O inter-actions, which link the mol-ecules into sheets parallel to the bc plane.
