title: 3-Methyl-6-trichloro-methyl-1,2,4-triazolo[3,4-b][1,3,4]thia-diazole.
abstract: In the crystal structure of the title compound, C(5)H(3)Cl(3)N(4)S, two mol-ecules related by a centre of symmetry demonstrate extremely short inter-molecular S⋯N contacts of 2.783 (2) Å. The crystal packing also exhibits π-π inter-actions indicated by a short distance of 3.340 (1) Å between the centroids of the triazole rings of neighbouring mol-ecules.
