4-(1-Cyclo­propyl-6-fluoro-4-oxo-1,4-dihydro­quinolin-7-yl)piperazin-1-ium 2,4,5-tricarb­oxy­benzene-1-carboxyl­ate monohydrate

In the crystal of title compound, C₁₆H₁₉FN₃O⁺·C₁₀H₅O₈⁻·H₂O, the water mol­ecule and the ions are connected by inter­molecular N—H...O and O—H...O hydrogen bonds and π–π stacking [centroid–centroid separation = 3.602 (1) Å] between the benzene ring and the pyridine ring, generating a three-dimensional supra­molecular structure.
