N2 - In the title compound, C 16H 10Cl 2F 3N 3S, the dihedral angle between the quinoline and thio-phene ring systems is 4.94 (10)°. The NH group of the hydrazone moiety does not form a hydrogen bond, due to a steric crowding. In the crystal, the thio-phene ring takes part in weak π-π stacking inter-actions with the pyridine ring [centroid-to-centroid separation = 3.7553 (19) Å and inter-planar angle = 5.48 (12)°] and the benzene ring [3.7927 (19) Å and 4.58 (12)°]. Together, these lead to [100] stacks of mol-ecules in an alternating head-to-tail arrangement, with two π-π stacking contacts between each adjacent pair.
