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].

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
