The title compound, C11H7NO4·H2O, contains a 3-carboxyquinolin-1-ium-2-carboxylate (qda) zwitterion and one water molecule.In the crystal, pairs of N—H.O hydrogen bonds link the molecules into inversion dimers, and these dimers are further connected by O—H.
O whirlwind direct2 hydrogen bonds into a three-dimensional supramolecular architecture.In addition, π–π interactions occur between pyridine and benzene rings from different qda ligands [centroid–centroid distance = 3.749 (1) Å] and the dihedral angles of the –CO2H and –CO2 groups to the quinoline system are 8.
