The mol-ecule of the title chalcone, C(23)H(15)BrO, is not planar and exists in the E configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 83.58 (6)°. The prop-2-en-1-one bridge makes dihedral angles of 63.00 (7) and 42.62 (16)° with the benzene and anthracene rings, respectively. In the crystal, mol-ecules are linked into dimers by weak C-H⋯O inter-actions. These dimers are arranged parallel to the bc plane and are further stacked al ...[more]
