Abstract

In the title compound, C22H13Cl2N5O3S2, the thia­diazine ring adopts a half-chair conformation. The benzene rings of the chloro­phen­oxy and chloro­benzyl groups and the thio­phene ring form dihedral angles of 35.6 (1), 80.7 (1) and 14.2 (1)°, respectively, with the triazole ring. In the crystal, mol­ecules are connected into sheets parallel to (11) by inter­molecular C—H⋯N and C—H⋯Cl hydrogen bonds. In addition, π–π stacking inter­actions are observed between thio­phene and triazole rings, and between inversion-related triazole rings [centroid–centroid distances = 3.5975 (11) and 3.4324 (11) Å]
