2,3,10,11-Tetrathiatricyclo[10.4.0.0(4,9)]hexadeca-4,6,8,12,14,16-hexaene (precession camera versus CCD).

The title compound, C(12)H(8)S(4), has crystallographic \overline{1} symmetry, the benzene groups thus being anti with respect to the plane of the four S atoms. The S-S and C-S bond lengths of the sulfur-carbon eight-membered ring were found to be similar to those in other structures containing such sulfur-carbon rings. There is evidence for pi-pi interactions between the aromatic rings of neighboring molecules, linking them into sheets.
