Iron(II) acetate is a coordination complex with formula Fe(CH3COO)2. It is a white solid, although impure samples can be slightly colored.[1] A light green tetrahydrate is also known, which is highly soluble in water.

Preparation and structure

Although ferrous acetate can be viewed as a simple salt, X-ray crystallography reveals a complicated polymeric structure.[1]

Iron powder reacts with acetic acid in electrolysis to give the ferrous acetate, with evolution of hydrogen gas:[1]

Fe + 2 CH3CO2H → Fe(CH3CO2)2 + H2

It can also be made from the insoluble, olive green, Iron(II) carbonate.Шаблон:Citation needed

It adopts a polymeric structure with octahedral Fe(II) centers interconnected by acetate ligands. It is a coordination polymer.[1]

A hydrated form be made by the reaction of ferrous oxide or ferrous hydroxide with acetic acid.[2]

Reaction of scrap iron with acetic acid affords a brown mixture of various iron(II) and iron(III) acetates that are used in dyeing.[3]

Uses

Ferrous acetate is used as a mordant by the dye industry. Ebonizing wood is one such process.[4]
