(E)-2-[2-(4-Carb-oxy-phen-yl)ethen-yl]-8-hydroxy-quinolin-1-ium chloride ethanol monosolvate.

ABSTRACT: 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 carb-oxy 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 mol-ecular geometry, two-dimensional aggregates are formed parallel to (221) via C-H?O, C-H?Cl, O-H?Cl and N-H?Cl hydrogen bonds. Inter-layer association is accomplished by O-Hethanol?Cl and O-H?Oethanol hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances vary from 3.6477?(12) to 3.8381?(11)?Å]. A supra-molecular three-dimensional architecture results from a stacked arrangement of layers comprising the ionic and hydrogen-bonded components.
