Molecular structure of N-(2-hydroxyethyl)pyridinium bromide

X-ray diffraction, structural analysis was employed to establish the structure of N-(2-hydroxyethyl)pyridinium bromide, C₇H₁₀NO⁺-Br^–. The plane of the pyridinium ring is twisted by 93 relative to the C-C bond of the side-chain. The N-C-C-O torsion angle is 63.6. The OH bond is oriented toward the heteroaromatic ring. The H-O-C-C torsion angle is 84.4. The molecular packing in the crystal lattice is such that the bromide ions are found between the heteroaromatic rings and the hydrogen bonded to the hydroxyl groups.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2617–2619, November, 1990.
