Cobalt(II) formate is an inorganic compound with the chemical formula Co(HCO2)2 (or Co(HCOO)2).[2] It typically exists as a dihydrate (Co(HCO2)2•2H2) in which it forms a 3D metal–organic framework structure and is known as Co-MOF.[3]

Cobalt(II) formate is a red crystalline solid and is soluble in water. It can be very hazardous to the environment. Cobalt formate is used to make catalysts for chemical manufacture[4] and for isolation of isotopically enriched hydrogen.
Synthesis
editIt can be prepared by adding Co(NO3)2 and phytic acid to a mixture of water, methanol, and dimethyl formamide.
The solution will have a clear appearance until it is heated 100 °C for about 24 hours. At this point it, will appear as a red crystalline structure.[3]
Application
editThis MOF has recently been used to isolate hydrogen isotopes. This is done via an oxygen evolution reaction using Co(HCOO)2 as a catalyst.[3]
