Abstract: In the crystal structure of the title compound [systematic name: N-(2,6-difluorophenyl)-5-methyl-1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide acetonitrile solvate], C₁₂H₉F₂N₅O₂S·C₂H₃N, the planar bicyclic triazolopyrimidine system is bound to the 2,6-difluorobenzene group via an SO₂-NH bridge, the C-S-N-C torsion angle being -77.85  (18)°; the dihedral angle formed by the bicyclic triazolopyrimidine system and the benzene ring is 128.0  (2)°. N-HN bonds link the molecules into infinite chains running along the a axis of the crystal structure.
