Dithiazole refers to heterocyclic compounds where the ring has the formula . The parent compounds have the formula . Cations with the same core are called dithiazolium compounds. Various isomers differ with respect to the location of the C, N, and S atoms. 1,2,3-Dithiazole has the sequence S-S-NH-CH-CH (all heteroatoms contiguous). Example: 1,2,4-Dithiazole has the sequence S-S-CH-NH-CH 1,3,2-Dithiazole has the sequence S-NH-S-CH-CH (all heteroatoms contiguous) 1,4,2-Dithiazole has the sequence S-NH-CH-S-CH
