Abstract

The asymmetric unit of the title salt solvate, C₁₇H₁₇F₆N₂O⁺·C₇H₅N₂O₄^–·1.5H₂O, comprises a piperidin-1-ium cation, a 3-amino-5-nitro­benzoate anion, and three fractionally occupied [i.e. 0.414 (3), 0.627 (6) and 0.459 (5)] disordered water mol­ecules of solvation. The cation has an L shape with a C-C-C-C torsion angle of -102.9 (3)° for the atoms linking the quinolinyl group to the rest of the cation. In the anion, the carboxyl­ate and nitro groups are essentially coplanar with the benzene ring [O-C-C-C torsion angle = 179.7 (2)° and O-N-C-C torsion angle = -3.9 (3)°]. In the crystal, extensive O-HO, O-HF and N-H·O hydrogen bonding leads to the formation of a layer in the ab plane.
