In the crystal, the two components are connected by an O¡ªH...N hydrogen bond. In the hydrogen-bonded unit, the dihedral angle between the quinoline ring system and the benzene ring of the benzoic acid is 44.75 (4)¡ã. The two components are further linked by intermolecular C¡ªH...O hydrogen bonds, forming a layer parallel to the ab plane. %U http://scripts.iucr.org/cgi-bin/paper?S1600536810046416
