In the title compound, C19H13ClF2N2O2, the conformation of the N—H bond in the amide segment isantito the C=O bond. The molecule is not planar, with dihedral angles between the central benzene ring and the outer benzene and pyridyl rings of 73.35 (7) and 81.26 (6)°, respectively. A weak intramolecular C—H...O hydrogen bond occurs. In the crystal, N—H...N, C—H...O and C—H...F hydrogen bonds lead to the formation of dimers. The N—H...N inversion dimers are linked by π–π contacts between adjacent pyridine rings [centroid–centroid = 3.8541 (12) Å] and C—H...π interactions. These contacts combine to stack the molecules along theaaxis.
