2'-(1,3-Dithiolan-2-ylidene)-4'-(1,3-dithiol-2-ylidene)spiro[1,3-dithiole-2,5'-(4' H -5',6'-dihydro-1',3'-dithiapentalene)], the Self-Condensation Product of an Extended Tetrathiafulvalene Derivative

Abstract : SiO2-​gel treatment of the extended tetrathiafulvalene derivative 2,​3-​bis(1,​4-​dithiafulven-​6-​yl)​-​6,​7-​dihydrotetrathiafulvalene, bearing two 1,​4-​dithiafulven-​6-​yl groups in vicinal positions, afforded the title compound, C14H10S8, as a cyclization product. While one dithiafulvenyl group is still conjugated with the tetrathiafulvalene moiety, the other one gives rise to a strongly folded 1,​3-​dithiole group linked to the molecule through a spiro-​C atom. Two short nonbonding intramolecular 1,​5-​S···S contacts are also identified in the title compound.
