1,3-Bis(naphthalen-2-ylmeth-yl)-1H-anthra[1,2-d]imidazole-2,6,11(3H)-trione
Abstract:
The title compound, C(37)H(24)N(2)O(3), is a 1H-anthra[2,1-d]imidazole-2,6,11(3H)-trione derivative having naphthyl-methyl substitutents attached to the imidazole N atoms. The anthraquinone part of the mol-ecule is somewhat folded along the the line connecting the carbonyl bonds. The dihedral angle between the two benzene rings is 7.8 (1)°. The two naphthyl systems of the substituents of the imidazole ring are positioned on the same side of the five-membered ring; these are approximately coplanar, the dihedral angle between the napthyl systems being 4.3 (2)°.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
