Abstract
The title compound, C12H10N2O2·H2O, crystallizes as a zwitterion in which the pyridine N atom is protonated and the carboxyl OH group is deprotonated. The benzene and pyridinium rings are inclined at a dihedral angle of 54.93 (1)°. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the molecules into a three-dimensional supramolecular network.
