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 theo-quinonoid type. The molecules are linked into sheets built from N—H...O, C—H...O and C—H...π(arene) hydrogen bonds, together with an aromatic π–π 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...π(arene) hydrogen bonds and aromatic π–π stacking interactions.
在 4-(4-氯苯胺基)-3-硝基苯甲酸甲酯(C14H11ClN2O4,Ⅰ)中,存在分子内 N-H...O氢键,分子内距离提供了新醌类电子极化的证据。这些分子由 N-H...O、C-H...O 和 C-H...π(芳香族)氢键以及芳香族 π-π 堆积相互作用连接成薄片。1-苄基-2-(4-氯苯基)-1H-苯并咪唑-5-羧酸甲酯(C22H17ClN2O2,Ⅱ)分子也连接成片状,这次是通过 C-H...π(芳香族)氢键和芳香族 π-π 堆积相互作用结合而成。
