Explanation

Potassium ferrioxalate is a chemical compound with the formula K3[Fe(C2O4)3], where iron is in the +3 oxidation state. It is an octahedral transition metal complex in which three bidentate oxalate ions are bound to an iron center. Crystals of the trihydrated form of the complex, K3[Fe(C2O4)3]·3H2O, are emerald green in colour. Potassium ferrioxalate is used in chemical actinometry.
