In the mol-ecule of the title compound, C17H15BrO3, the rings make a dihedral angle of 75.54 (17)°. In the crystal structure, inter-molecular C - H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, and the π-stacked dimers inter-act with neighbouring dimers via C - H⋯π stacking inter-actions. © Intern...
