The asymmetric unit of the title compound, C10H6N2S2, contains two crystallographically independent but conformationally similar mol-ecules. The fused thio-phene ring cores are almost planar [maximum deviation = 0.027 (3) Å] with the thio-phene rings forming dihedral angles of 0.5 (4)° in one mol-ecule and 1.91 (4)° in the other. The crystal packing is stabilized only by van der Waals inter-actions.
