4-Amino-3,5-dichloropyridinium 3-hydroxypicolinate monohydrate

Abstract

In the title hydrated salt, C5H5Cl2N2+·C6H4NO3−·H2O, the pyridine N atom of the cation is protonated and an intramolecular O—H...O hydrogen bond is observed in the anion, which generates an S(6) ring. The crystal packing features N—H...N, O—H...O, N—H...O, C—H...Cl and C—H...O hydrogen bonds, which generate a three-dimensional network.
