Nickel dicyanide is the

inorganic compound In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...

with a chemical formula Ni(CN)₂. It is a gray-green solid that is insoluble in most solvents.

Production

Addition of two equivalents of sodium or potassium cyanide to a solution of nickel(II) ions in aqueous solution leads to the precipitation of nickel(II) cyanide tetrahydrate. On heating the tetrahydrate to 140 °C, this hydrate converts to anhydrous nickel(II) cyanide.
