Abstract:
In the title compound, C(26)H(16)ClN(3)O(3), the dihedral angle between the anthracene mean plane and imidazole ring is 64.75 (2)°. In the crystal, π-π inter-actions between anthracene fragments lead to the formation of stacks of mol-ecules propagating in [100]. The short distance between the carbonyl groups of symmetry-related molecules [C⋯O = 2.985 (2) Å] indicates the existence of dipole-dipole inter-actions. The crystal packing also exhibits short inter-molecular contacts between the nitro groups and Cl atoms [Cl⋯O = 3.181 (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...
