Nickel formate is the nickel salt of formic acid with the chemical formula Ni(HCOO)2.

Contents

Synthesis and structure

Nickel formate can be obtained by reacting nickel(II) acetate or nickel(II) hydroxide [3] with formic acid. [5]

Ni(OH)2 + 2HCOOH → Ni(HCOO)2 + 2 H2O

Nickel formate can also be synthesized by the reaction of sodium formate with nickel (II) sulphate. [3]

Characteristics

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]

Ni(HCO2)2(H2O)2 → Ni + 2 CO2 + 2 H2O + H2

Such fine powders are useful as hydrogenation catalysts. [7]

Use

Nickel formate is used in the production of nickel and other nickel compounds such as nickel catalysts. [4]
