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—H⋯N bonds link the molecules into infinite chains running along the a axis of the crystal structure.
