چکیده
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.

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-carb-oxy-lic acid to the other; their N and O atoms are cis to each other in the distorted octa-hedral coordination geometry. The K atom is also coordinated by another monodentate quinoline-2-carb-oxy-lic acid; the acid is disordered with respect to...

In the title structure, C(25)H(24)FN(3)O(5), a strong intra-molecular O-H⋯O hydrogen bond is present between the carb-oxy group at the 3-position and the carbonyl group at the 4-position. In the crystal, mol-ecules are held together by weak C-H⋯O, C-H⋯F and π-π [centroid-centroid distance 3.6080 (8) Å] inter-actions. The 1,4-dihydro-quinoline ring and cyclo-propyl group are not in the same plan...
