The cyanide ion − C≡N is isoelectronic with carbon monoxide − C≡O + and with molecular nitrogen N≡N. A triple bond exists between C and N. The negative charge is concentrated on carbon C. [3] [4]

Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
Cyanogen azide is a chemical compound with the chemical formula C N 4, or more precisely − N=N + =N−C≡N. It is an azide compound of carbon and nitrogen. It is an oily, colourless liquid at room temperature. [2] It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form.
Sodium cyanide is a compound with the formula Na C N and the structure Na + − C≡N. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt .
The structure of silver cyanide consists of -[Ag-CN]- chains in which the linear two-coordinate Ag + ions are bridged by the cyanide ions, [3] typical of silver(I) and other d 10 ions. This is the same binding mode as seen in the more famous case of Prussian blue .
It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment. Although many salts of cyanide are highly toxic, ferro- and ferricyanides are less toxic because they tend not to release free cyanide. [1]
