Cobalt(II) formate is an

hydrate (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

It 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

This 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]
