2-Amino-6-methyl-pyridinium 2-hy-dr-oxy-benzoate

摘要

In the title mol-ecular salt, C6H9N2+·C7H5O3?, the cation is protonated at its pyridine N atom and and makes a dihedral angle of 16.26?(9)° with the plane of the six-membered ring of the anion. The six-membered ring makes a dihedral angle of 6.09?(3)° with the attached carboxyl-ate group. In the anion, an intra-molecular O—H?O hydrogen bond generates an?S(6) ring motif and a pair of N—H?O hydrogen bonds generates an?R22(8) ring motif. In the crystal, the anions and cations are linked?via?N—H?O hydrogen bonds to form a tetra-mer.
