The title molecule, C10H4O2S2, is situated on a crystallographic center of inversion. In the crystal, weak hydrogen bonding contributes to the packing of the molecules.
This dione was synthesized according to modified literature procedures, see: Beimlung & Kossmehl (1986 ▶); Slocum & Gierer (1976 ▶). It is a precursor to many different semiconducting polymeric compounds and the structure is important in that it appears as crystalline products in poorly purified materials, see: Hundt et al. (2009 ▶); Subramaniyan et al. (2011 ▶); Yamamoto et al. (2011 ▶). For weak intermolecular interactions, see: Janiak (2000 ▶); Sinnokrot et al. (2002 ▶).
