2-Amino-3-methylpyridinium acetate

M. Odabasoglu and O. Büyükgüngör

Abstract: The title compound, C₆H₉N₂⁺·C₂H₃O₂^-, contains eight- and sixteen-membered hydrogen-bonded rings involving 2-amino-3-methylpyridinium and acetate ions. The 2-amino-3-methylpyridinium and acetate ions are linked into zigzag chains by C-HO and N-HO hydrogen bonds. The dihedral angle between the 2-amino-3-methylpyridinium ring and the hydrogen-bonded acetate ion is 6.63 (6)°. The heterocycle is fully protonated, enabling amine-imine tautomerization.
