Abstract: The title compound, C₁₄H₉F₆N₃S, exhibits a nearly planar conformation in the solid state, with a dihedral angle between the planes of the benzene and pyridine rings of 14.86 (3)°. The pyridine N atom allows for the formation of a six-membered N-HN_py hydrogen-bonded ring, thus forcing the two amide H atoms of the thiourea group to point in opposite directions. The second N-H group forms an intermolecular N-HS hydrogen bond with the S atom of an adjacent molecule. The F atoms of the two trifluoromethyl groups display rotational disorder around the C-CF₃ axis, with an occupancy ratio of 0.54 (1):0.46 (1).
