Abstract: In the title compound, C₁₇H₁₂F₂N₄S, the five-membered triazole ring and two benzene rings are planar, while the six-membered thiadiazole ring is slightly distorted, with a mean deviation of 0.234 Å. Both the ring S and adjacent non-bridgehead C atom deviate significantly [0.320 (2) and 0.370 (2) Å] from the thiadiazole plane. In the crystal structure, four different kinds of intra- and intermolecular C-HN hydrogen-bonding interactions are observed, leading to the formation of a one-dimensional zigzag chain along the crystallographic b axis.
