(5E)-2-[4,5-Bis(methylsulfanyl)-1,3-dithiol-2-ylidene]-5-(4-iodo-1,3-dithiol-2-ylidene)-1,3-dithiolan-4-one

The molecular framework of the title compound, C(11)H(7)IOS(8), is almost planar [maximum deviation = 0.040 (4) angstrom], except for the two methylsulfanyl groups, which are twisted relative to the molecular skeleton, making C-S-C-C torsion angles of 144.1 (8) and -141.3 (8)degrees. In the crystal, molecules are stacked alternately in opposite orientations, forming a one-dimensional column parallel to [110]. The primary interactions between molecules comprising the columns are of the S center dot center dot center dot S type [3.554 (1) angstrom]. Interactions between columns are of the S center dot center dot center dot S type [3.411 (1) along b and 3.444 (1) angstrom along c], as well as S center dot center dot center dot I contacts [3.435 (2) angstrom].
