N-Paranitrophénylhydrazono-α-(2-méthylbenzimidazol-1-yl)glyoxylate d'éthyle

Abstract

There are two independent molecules in the asymmetric unit of the title compound {systematic name: ethyl 2-(2-methyl-1H-benzimidazol-1-yl)-2-[2-(4-nitrophenyl)hydrazinylidene]ethanoate}, C18H17N5O4. Each molecule and its inversion-related partner are linked by a pair of intermolecular N—H...N hydrogen bonds, forming inversion dimers in the crystal structure.
