5,5′-Dimethyl-2,2′-dithiodi-1,3,4-thiadiazole
Acta Crystallographica Section E Structure Reports Online, 2002 The title compound, C6H6N4S4, is formed through the thionato S—S bonding of parent 2-mercapto-5-methyl-1,3,4-thiadiazole molecules, following the deprotonation of thiol groups in a mixed solvent. The title compound crystallizes in the monoclinic system, space group C2/c. The S—S distance is 2.028 (1) A, typical of a single bond.
