چکیده

In the title compound, C(15)H(11)BrO(4), the dihedral angle between the aromatic rings is 66.77 (8)°. In the crystal, O-H⋯O, C-H⋯Br and C-H⋯O hydrogen bonds link the mol-ecules, forming layers lying parallel to (101). The crystal packing is further consolidated by C-H⋯π inter-actions and π-π stacking inter-actions [centroid-centroid distance = 3.5476 (7) Å].
