6,6-Dimethyl-2H,5H,6H,7H-1,3-dithiolo[4,5-f][1,5,3]dithiasilepin-2-one

Abstract

In the structure of the title compound, C7H10OS4Si, the carbonyl O atom lies in the plane of the five-membered dithiole ring with a deviation of only 0.022 (2) Å. The seven-membered ring adopts a chair conformation. The crystal packing is stabilized by S...O [3.096 (4) Å] and S...S [3.620 (4) Å] contacts, together with C—H...S interactions.
