The crystal and molecular structures of [4-((E)-but-1-enyl)-2,6-dimethoxyphenyl]pyridine-3-carboxylate (BDMP) and [4-((E)-pent-1-enyl)-2,6-dimethoxyphenyl]pyridine-3-carboxylate (PDMP) are investigated by low-temperature X-ray diffraction measurements. The geometries of these molecules indicate that intramolecular dihydrogen bonds may exist for these structures. The use of the Bader theory supports
