Preparation of Pure Sample of Potassium Trioxalatoferrate (III)

Potassium trioxalatoferrate (III) is an octahedral transition metal complex with the formula K3[Fe(C2O4)3], in which three bidentate oxalate ions are bound to an iron center. The central iron atom is in the +3 oxidation state. This complex can be prepared by dissolving freshly prepared ferric hydroxide in a solution of potassium oxalate and oxalic acid.
