Dicyanamide

Dicyanamide, also known as dicyanamine, is an anion having the formula. It contains two cyanide groups bound to a central nitrogen anion. Dicyanamide is formed by decomposition of 2-cyanoguanidine.
Dicyanamide is used extensively as a counterion of organic and inorganic salts, as it is a "chemically inert, hydrophobic anion" and pseudohalide. It is also as a reactant for the synthesis of various covalent organic structures.
Dicyanamide was used as an anionic component in an organic superconductor that was, when reported in 1990, a superconductor with the highest transition temperature in its structural class.
Dean Kenyon examined the role of this chemical in reactions that can produce peptides, and a co-worker examined dicyanamide's possible role in primordial biogenesis.
