Sodium maleonitriledithiolate explained

Sodium maleonitriledithiolate is the chemical compound described by the formula . The name refers to the cis compound, structurally related to maleonitrile . Maleonitriledithiolate is often abbreviated mnt. It is a "dithiolene", i.e. a chelating alkene-1,2-dithiolate. It is a prototypical non-innocent ligand in coordination chemistry. Several complexes are known, such as .^[1] The salt is synthesized by treating carbon disulfide with sodium cyanide to give the cyanodithioformate salt, which eliminates elemental sulfur in aqueous solution:^[2]

The compound was first described in 1958.^[3]
