چکیده
In the title compound, C(17)H(11)N(5)S(2), the dihedral angles formed between the triazole ring and the benzene ring and the 1,3-benzothia-zole ring system are 8.67 (8) and 13.90 (9)°, respectively. The conformation of the triazolo-thia-diazin-3-yl fused ring system is a twisted half-chair. Overall, the mol-ecule adopts a flattened shape. Supra-molecular helical chains along the a axis sustained by C-H⋯N inter-actions are found in the crystal structure. These are linked via C-H⋯π contacts as well as π-π [centroid-centroid distance = 3.5911 (12) Å] inter-actions between the triazole and thia-zole rings.
