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

Abstract

The molecular framework of the title compound, C11H6I2OS8, is almost planar [maximum deviation = 0.057 (5) Å] except for the two methylsulfanyl groups, which are twisted relative to the molecular skeleton, with C—C—S—C torsion angles of 49.74 (22) and 82.91 (21)°. In the crystal, molecules are stacked alternately in opposite orientations, forming a one-dimensional column along the b axis. The interaction between adjacent columns is accomplished through S...S [3.4289 (5) Å], S...I [3.4498 (4) Å] and O...I [2.812 (2) Å] contacts.
