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

Abstract

The molecular framework of the title compound, C11H7IOS8, is almost planar [maximum deviation = 0.040 (4) Å], 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)°. 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...S type [3.554 (1) Å]. Interactions between columns are of the S...S type [3.411 (1) along b and 3.444 (1) Å along c], as well as S...I contacts [3.435 (2) Å].
