Ferrous oxalate, or iron(II) oxalate, is a chemical compound consisting of one iron(II) ion (Fe2+) and one oxalate ion (C2O42−). It has the chemical formula Fe[C2O4].

Iron(II) oxalate is more commonly encountered as the dihydrate, Fe[C2O4]·2H2O, CAS # 6047-25-2. Its crystal structure consists of chains of oxalate-bridged iron atoms, capped by water molecules.[1]
