Abstract

In the title compound, C(12)H(11)FN(4)S, the thia-diazine ring adopts a twist-boat conformation. The dihedral angle between the triazolothia-diazine system and the benzene ring is 10.54 (9)°. The crystal structure is characterized by C-H⋯N hydrogen bonds. The crystal packing also exhibits π-π inter-actions, with a centroid-centroid distance of 3.6348 (15) Å.
