Iron(II) acetate is an coordination complex with formula Fe(C2H3O2)2. It is a white solid although impure samples can be slightly colored. A light green tetrahydrate is also known, which is highly soluble in water.
Preparation and structure
Iron powder reacts with hot acetic acid to give the product:[1]
- Fe + 2 CH3CO2H → Fe(CH3CO2)2 + H2
It adopts a polymeric structure with octahedral Fe(II) centers bridged by acetate ligands. It is not a salt.[1]
The hydrate can be made by the reaction of ferrous oxide or ferrous hydroxide with acetic acid.[4]
Reaction of scrap iron with acetic acid affords a brown mixture of various iron(II) and iron(III) acetates that are used in dying.[5]
Uses
Ferrous acetate is used as a mordant by the dye industry. Ebonizing wood is one such process.[6]
