Sodium maleonitriledithiolate is the chemical compound described by the formula Na2S2C2(CN)2. The name refers to the cis compound, formally derived from maleonitrile. This is the most common salt of the dianion, maleonitriledithiolate, often called mnt, which is a "dithiolene", i.e. a chelating alkene-1,2-dithiolate that serves as a non-innocent ligand for transition metals and is commonly used in coordination chemistry. Several complexes are known, such as [Ni(mnt)2]2−.[1]:143-146
The salt is synthesized by treating carbon disulfide with sodium cyanide to give the cyanodithioformate salt, which eliminates elemental sulfur in aqueous solution:[2]
- 2 NaCN + 2 CS2 → Na2S2C2(CN)2 + 1/4 S8
The compound was first described by Bähr and Schleitzer 1958.[3]
