In the title compound, C18H14NO3+·Cl−·CH3CH2OH, the dihedral angle formed by the mean planes of the quinolinium and benzene rings is 3.4 (1)°, while the carboxy substituent is tilted at an angle of 4.8 (1)° with respect to the benzene ring. There is a short N—H
O contact in the cation. In the crystal, due to the planar molecular geometry, two-dimensional aggregates are formed parallel to (221) via C—HO, C—HCl, O—HCl and N—HCl hydrogen bonds. Interlayer association is accomplished by O—HethanolCl and O—HOethanol hydrogen bonds and π–π stacking interactions [centroid–centroid distances vary from 3.6477 (12) to 3.8381 (11) Å]. A supramolecular three-dimensional architecture results from a stacked arrangement of layers comprising the ionic and hydrogen-bonded components.
