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 dmit^2- 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]
