چکیده
In the title compound, C(14)H(11)FN(6)S, the 1,2,4-triazolo[3,4-b][1,3,4]thia-diazole ring system is essentially planar [maximum deviation = 0.022 (3) Å] and is inclined at dihedral angles of 15.00 (18) and 52.82 (16)° with respect to the pyrazole and phenyl rings. In the crystal, mol-ecules are linked into two-dimensional networks parallel to (100) via inter-molecular N-H⋯N and weak C-H⋯N hydrogen bonds. The crystal packing is further consolidated by weak π-π stacking inter-actions, with a centroid-centroid distance of 3.590 (2) Å. The crystal studied was an inversion twin with a 0.37 (13):0.63 (13) domain ratio.
