(E)-3-(Anthracen-9-yl)-1-(4-bromo-phen-yl)prop-2-en-1-one.

In the title mol-ecule, C(23)H(15)BrO, the prop-2-en-1-one unit is planar and it makes dihedral angles of 20.9 (1) and 45.8 (1)°, respectively, with the 4-bromo-phenyl ring and the anthracene ring system. The interplanar angle between the 4-bromophenyl ring and the anthracene ring system is 35.52 (7)°. In the crystal structure, mol-ecules are linked into dimers by C-H⋯Br hydrogen bonds, and the dimers are linked into a zigzag network parallel to the bc plane by weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions involving the central benzene ring of the anthracene ring system.
