| The title compound, an octamer CgSg of carbon sulfide, is obtained by reacting diethyl dihydroxythieno[2,3-b]thiophenedicarboxylate with the Lawesson reagent in the presence of sulfur. The crystal structure shows three-dimensional sulfur-sulfur interactions. C arbon sulfide (1) rapidly polymerizes [1]. Its dimer 2 [2-6] and hexamer 3 [7-9] could be de tected by neutralization-reionization mass spectro metry. A t room tem perature, only the nonamers 4 [10, 11] and 5 [12] are stable compounds.
