Nickel formate is the nickel salt of formic acid with the chemical formula Ni(HCOO)2.
Nickel formate can be obtained by reacting nickel(II) acetate or nickel(II) hydroxide [3] with formic acid.[5]
Nickel formate can also be synthesized by the reaction of sodium formate with nickel (II) sulphate.[3]
As a dihydrate, nickel formate is a green, odorless, non-flammable solid that is sparingly soluble in water.[2] The compound has a monoclinic crystal structure.[3] The anhydride forms on careful heating at 130–140 °C.[6] When heated in a vacuum to 300 °C, pure nickel is formed:[5]
Such fine powders are useful as hydrogenation catalysts.[7]
Nickel formate is used in the production of nickel and other nickel compounds such as nickel catalysts.[4]
