Hydrogen-bonded sheet structures in methyl 4-(4-chloroanilino)-3-nitrobenzoate and methyl 1-benzyl-2-(4-chlorophenyl)-1H-benzimidazole-5-carboxylate

Abstract: In methyl 4-(4-chloroanilino)-3-nitrobenzoate, C14H11ClN2O4, (I), there is an intramolecular N-H...O hydrogen bond and the intramolecular distances provide evidence for electronic polarization of the o-quinonoid type. The molecules are linked into sheets built from N-H...O, C-H...O and C-H...[pi](arene) hydrogen bonds, together with an aromatic [pi]-[pi] stacking interaction. The molecules of methyl 1-benzyl-2-(4-chlorophenyl)-1H-benzimidazole-5-carboxylate, C22H17ClN2O2, (II), are also linked into sheets, this time by a combination of C-H...[pi](arene) hydrogen bonds and aromatic [pi]-[pi] stacking interactions.

Formula: C14H11ClN2O4 and C22H17ClN2O2
