title: 2-(4-Methyl-phen-yl)quinoline-4-carb-oxy-lic acid.
abstract: In the title compound, C(17)H(13)NO(2), the dihedral angle between the plane of the carb-oxy group and the quinoline mean plane is 45.05 (13)°, and that between the toluene ring mean plane and the quinoline mean plane is 25.29 (7)°. In the crystal, molecules are linked via O-H⋯.N hydrogen bonds, forming chains propagating along the b-axis direction. These chain are linked via C-H⋯O interactions, forming two-dimensional networks lying parallel to the ab plane.
