In organosulfur chemistry, 1,3-dithioles are a class of heterocycles based on the parent compound 1,3-dithiacyclopentene (also known as 1,3-dithiole). The ligand dmit2- is a 1,3-dithiole.[1] Heating solutions of Na2dmit gives the isomeric disulfide, a 1,2-dithiole.

Structure of the anion [Zn(dmit)2]2-, featuring two 1,3-dithiole-4,5-dithiolate ligands complexed to zinc.[2]
