The unit cell of the title compound, C36H36N2, contains two independent mol­ecules which are located about inversion centers. In each molecule the quinoline rings are almost planar, with mean deviations of 0.0302 (1) and 0.0173 (1) Å. In the crystal, mol­ecules are linked by C—H⋯π inter­actions into a three-dimensional network.

In the mol­ecule of the title compound, C15H12ClF2NO3, the quinoline ring system is not planar, the dihedral angle between the pyridine and benzene rings being 3.55 (8)°. In the crystal, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into layers parallel to (101).

In the title compound, C14H10N2O2, the dihedral angle between the heterocyclic ring system and the phenyl ring is 45.8 (5)°. Weak inter­molecular C—H⋯N hydrogen bonding is present in the crystal structure.
