The asymmetric unit of the title compound, C10H8N2S2, is composed of two independent half-molecules, each residing on a center of symmetry. In the crystal, weak C-H interactions join the two symmetry-independent molecules together into interlinked chains parallel to . The crystal structure was refined as a two-component pseudo-merohedral twin using the twin law 001 0-10 100. The refined domain fractions are 0.516 (3) and 0.484 (3).
