2-Amino-5-methylpyridinium 6-oxo-1,6-dihydropyridine-2-carboxylate
The anion of the title salt, C6H9N2 +·C6H4NO3 −, undergoes an enol-to-keto tautomerism during the crystallization. In the crystal structure, the cation and anion are held together by a relatively short N—H⋯O hydrogen bond, and the two anions are further connected to each other by a pair of N—H⋯O hyd...
