The K atom in the title complex, [K(C(10)H(6)NO(2))(C(10)H(7)NO(2))(3)], lies on a twofold rotation axis that relates one N,O-chelating quinoline-2-carboxylic acid to the other; their N and O atoms are cis to each other in the distorted octahedral coordination geometry. The K atom is also coordinated by another monodentate quinoline-2-carboxylic acid; the acid is disordered with respect to a monodentate quinoline-2-carboxylate anion; the acid and anion are linked by an O-H...O hydrogen bond. An O-H...N hydrogen bond links adjacent molecules into a linear chain structure along the a axis.
