title: 1,3-Dimethyl-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[c]thio-phene-4,8-dione.
abstract: In the title compound, C(11)H(12)O(2)S, the C and S atoms of the central thio-phene and the methyl groups, and the two carbonyl groups of the cyclo-hepta-nedione are almost coplanar [maximum deviation from the mean plane = 0.221 (2) Å]. The packing is stabilized by π-π inter-actions between the conjugated thio-phenes, the shortest centroid-centroid distance between thio-phene rings being 3.9759 (10) Å.
