【 摘 要 】

The crystal structure of the title compound, C9H6OS2, represents a new polymorph. The crystal structure was solved in the ortho­rhom­bic space group Pbcn with one half of the mol­ecule in the asymmetric unit. The thio­phene rings are perfectly planar and twisted with respect to each other, showing the mol­ecule to be in an S,O-trans/S,O-trans conformation. In the crystal, C—H⋯O hydrogen bonds connect the mol­ecules into layers extending parallel to the ab plane. The crystal structure also features π–π inter­actions.
