title: 4-(5-Chloro-thio-phen-2-yl)-1,2,3-selenadiazole.
abstract: In the title compound, C6H3ClN2SSe, the selenadiazole and chloro-thio-phene rings are almost coplanar [dihedral angle = 5.24 (15)°]. In the crystal, C-H⋯N inter-actions link the mol-ecules into chains extending along the b-axis direction. C-H⋯π inter-actions also occur.
