Abstract

Nickel compounds can be divided into the classic inorganic salts and a wide variety of organonickel compounds. The various compounds find use as plating salts, catalysts, in specialty ceramics and chemicals, as pigments, and in nickel metal refining. Commercially the most important are the inorganic nickel(II) compounds and nickel carbonyl, a highly toxic nickel(0) species.

Nickel salts form a wide variety of complexes with nitrogen, phosphorus, and sulfur, as well as with oxygen and carbon -systems. Properties, manufacture, and uses of nickel compounds and complexes are discussed.
