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

Extraction and presentation

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

It is also possible to produce it by reacting sodium formate with nickel (II) sulfate .


As a dihydrate, nickel formate is a green, odorless, non-flammable solid that is sparingly soluble in water. The compound has a monoclinic crystal structure . When carefully heated, the anhydrate forms at 130–140 ° C. When heated in a vacuum to 300 ° C, pure nickel is produced.


Nickel formate is used to make nickel and other nickel compounds such as nickel catalysts.
