In chemistry, dithiadiazoles are a family of heterocyclic compounds with the formula RCN2S2. Although several isomers are possible, the 1,2,3,5-dithiadiazoles have received greater attention. The neutral compounds are radicals with 7 π electrons. Oxidation affords the dithiadiazolium cations.[1] Chloride salts of diithiadiazolium cation can be prepared by the reaction of nitriles with thiazyl chloride: RCN + 2 NSCl → [RCN2S2]Cl + 1/2 Cl2 + 1/2 N2 References1. ^{{cite journal|authors=Jeremy M.
