Ferrous oxalate

Описание

Ferrous oxalate, or iron (II) oxalate, is a chemical compound consisting of one iron (II) ion (Fe²⁺) and one oxalate ion (C₂O₄^2-). It has the chemical formula FeC₂O₄.
Iron(II) oxalate is more commonly encountered as the dihydrate, FeC₂O₄·2H₂O . Its crystal structure consists of chains of oxalatebridged iron atoms, capped by water molecules.
When heated, it dehydrates and decomposes into carbon dioxide, carbon monoxide, iron oxides and pyrophoric black iron.
