Cobalt Acetate

Cobalt(II) acetate is the cobalt(II) salt of acetic acid. It may also be found as the tetrahydrate.

It may be formed by the reaction between cobalt oxide or hydroxide and acetic acid:

    CoO + 2 HC2H3O2 → Co(C2H3O2)2 + H2O

Cobalt(II) acetate may be reacted with salenH2 to give salcomine, an oxygen-transport compound:[1]

    Co(OAc) + salenH2 → Co(salen) + 2 HOAc

Cobalt(II) acetate is harmful if swallowed or inhaled. It may cause an allergic skin reaction. Chronic exposure may affect heart, thyroid, lungs, and kidneys.
