What Are The Physical And Chemical Properties Of Nickel Ii Cyanide?

Nickel II cyanide (Ni(CN)2) is a greenish-white compound with a molecular weight of 122.71 g/mol. It is sparingly soluble in water and soluble in acids.

The physical properties of Ni(CN)2 include a melting point of 600 °C and a density of 1.87 g/cm3. It has a crystalline structure and is classified as a coordination compound.

Chemically, Ni(CN)2 is a strong oxidizing agent and reacts readily with reducing agents. It can be decomposed by heat or acid to release toxic hydrogen cyanide gas. Ni(CN)2 is stable in dry air but can slowly decompose in the presence of moisture or carbon dioxide to form nickel carbonate and cyanogen gas.
