|Section2= |Section3= }} Sodium maleonitriledithiolate is the chemical compound described by the formula Na2S2C2(CN)2. The name refers to the cis compound, formally derived from maleonitrile. The dianion is a "dithiolene", i.e. a chelating alkene-1,2-dithiolate that serves as a non-innocent ligand for transition metals. Several complexes are known, such as ()2−. The salt is synthesized by treating carbon disulfide with sodium cyanide to give the cyanodithioformate salt, which eliminates elemental sulfur in aqueous solution:〔R. H. Holm, A.
