Chemistry:Dicyanamide
Dicyanamide, also known as dicyanamine, is an anion having the formula C2N−3. 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.[1] 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.[2]
Dean Kenyon examined the role of this chemical in reactions that can produce peptides,[3] and a co-worker examined dicyanamide's possible role in primordial biogenesis.[4]
