Dicyanamide

Not to be confused with Dicyandiamide.

Dicyanamide, also known as dicyanamine, is an anion having the formula C
₂N⁻
₃. It contains two cyanide groups bound to a central nitrogen anion. The chemical is formed by decomposition of 2-cyanoguanidine. It is used extensively as a counterion of organic and inorganic salts, and 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.^[1]

Dean Kenyon examined the role of this chemical in reactions that can produce peptides,^[2] and a co-worker examined dicyanamide's possible role in primordial biogenesis.^[3]
