5-(4,5-Diiodo-1,3-dithiol-2-ylidene)-4′,5′-bis(methylsulfanyl)-2,2′-bi-1,3-dithiole-4(5H)-thione

Abstract

The molecular skeleton of the title molecule, C11H6I2S9, is nearly planar [maximum deviation 0.052 (3) Å] except for the two methyl groups. In the crystal, molecules related by translation along b axis are associated into columns through π–π interactions between the five-membered rings, with a centroid–centroid distance of 3.593 (5) Å. Interaction between adjacent columns is accomplished by short S...I contacts of 3.2099 (4) Å.
