In the title 1:1 adduct, C9H7N·C7H7NO2, the carboxyl group is twisted at an angle of 5.42 (8) Å with respect to its attached benzene ring. In the crystal, the carboxylic acid molecule is linked to the quinoline molecule by an O—H...N hydrogen bond. The 4-aminobenzoic acid molecules are linked by N—H...O hydrogen bonds, forming sheets propagating in (001). Weak aromatic π–π stacking [centroid-to-centroid distances = 3.758 (1) and 3.888 (1) Å] interactions also occur.
