3-Carb­oxy­quinolin-1-ium-2-carboxyl­ate monohydrate

The title compound, C(11)H(7)NO(4)·H(2)O, 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 hydrogen bonds into a three...

Sumario:The title compound, C(11)H(7)NO(4)·H(2)O, 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 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 –CO(2)H and –CO(2) groups to the quinoline system are 8.47 (3) and 88.16 (6)°, respectively.
