چکیده
In the title compound, C(20)H(15)F(6)N(3)O(2), the quinoline ring system is almost coplanar with the benzene ring; the dihedral angle between the two planes is 2.31 (8)°. The crystal structure displays an inter-molecular C-H⋯F hydrogen bond. In addition, a weak π-π inter-action is observed between the unfused benzene ring and the benzene ring of quinoline, with a centroid-centroid distance of 3.586 (1) Å.

The title mol-ecule, C(25)H(22)F(6)N(2)O(3), adopts an open conformation whereby the quinoline and carboxyl-ate ester groups are orientated in opposite directions but to the same side of the piperidine ring so that the mol-ecule has an approximate U-shape. The piperidine ring adopts a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate ...
