- Аннотация: The title compounds, 2-(4-hexyloxyphenyl)-1H-benzimidazole (C19H22N2O; 1), 2-(4-hexyloxyphenyl)-1-phenyl-1H-benzimidazole (C25H26N2O; 2) and 1-benzyl-2-(4-hexyloxyphenyl)-1H-benzimidazole (C26H28N2O; 3) were synthe- sized and their structures were determined by single-crystal X-ray analysis. The N-substituent at the imidazole moiety slightly affects the interplanar angle between the 4-hexyloxyphenyl ring and the benzimidazole system. The unsubstituted benzimidazole (1) forms intermolecular N—H...N bonds while in the crystal structures of 2 and 3, the molecules are assembled only through pi–pi and C—H...pi interactions.
