Abstract

In the title compound, C16H10Cl2F3N3S, the dihedral angle between the quinoline and thio­phene 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 thio­phene ring takes part in weak π–π stacking inter­actions with the pyridine ring [centroid-to-centroid separation = 3.7553 (19) Å and inter­planar angle = 5.48 (12)°] and the benzene ring [3.7927 (19) Å and 4.58 (12)°]. Together, these lead to [100] stacks of mol­ecules in an alternating head-to-tail arrangement, with two π–π stacking contacts between each adjacent pair
