Özet

In the title compound, C14H16O4S2, the thieno[2,3-b]thiophene ring systems are planar [maximum deviation = 0.008 (2) angstrom]. The molecular conformation is stabilized by intramolecular C-H center dot center dot center dot O hydrogen bonds, while the crystal packing is stabilized by C-H center dot center dot center dot O, C-H center dot center dot center dot pi and pi-pi stacking [centroid-centroid distance = 3.6605 (14) angstrom] interactions, which lead to supramolecular layers in the ab plane.
