(E)-3-(Anthracen-9-yl)-1-(2-bromo-phen-yl)prop-2-en-1-one.

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 along the a axis by π-π inter-actions with a centroid-centroid distance of 3.7561 (9) Å. The crystal structure is further stabilized by C-H⋯π inter-actions.
