title: (Z)-3-(9-Anthr-yl)-1-(4-bromo-phen-yl)-2-(4-nitro-1H-imidazol-1-yl)prop-2-en-1-one.
abstract: In the title mol-ecule, C(26)H(16)BrN(3)O(3), the anthracene and benzene mean planes make dihedral angles of 63.79 (2) and 14.67 (2)°, respectively, with the plane of the imidazole ring. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules to form centrosymmetric dimers. Weak π-π stacking inter-actions, with centroid-centroid distances of 3.779 (2) and 3.826 (2) Å, supply additional stabilization. The crystal packing also exhibits short inter-molecular contacts between the nitro groups and Br atoms [Br⋯O = 3.114 (2) Å].
