The title compound, C17H12N2O, was synthesized by an ether synthesis from quinolin-6-ol and 4-(bromomethyl)benzonitrile. The phenyl ring of the benzonitrile group makes a dihedral angle of 47.52 (6)° with the plane of the quinoline fragment. The crystal structure is stabilized by intermolecular C—H...π interactions between a benzene H atom of the benzonitrile group and the benzene ring of the quinoline fragment. In addition, the crystal structure also exhibits a weak intermolecular C—H...N hydrogen bond.

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.

In the crystal structure of the title compound, C11H14N2OS, the six atoms of the central C2N2OS residue are coplanar (r.m.s. deviation = 0.002 Å), which facilitates the formation of an intramolecular N—H...O hydrogen bond, which closes anS(6) loop. The terminal phenyl ring is inclined with respect to the central plane [dihedral angle = 42.10 (6)°]. The most prominent feature of the crystal packing is the formation of {...HNCS}2synthons resulting in centrosymmetric dimers.
