Chemical compound
Nickel formate is the nickel salt of formic acid with the chemical formula Ni(HCOO)2 .
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 H2 O
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 (H2 O)2 → Ni + 2 CO2 + 2 H2 O + 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]
