Description and Uses

Iron(II) oxalate, FeC204.2H20, is precipitated as yellow crystals from solutions containing iron(II) and oxalate ions ; in the presence of excess alkali metal oxalate, however, soluble oxalato complexes M2[Fe(C2O4)2] are formed which can be precipitated by the addition of alcohol. The oxalate is paramagnetic with μeff= 5·2 B.M. at room temperature.
