Chemical compound
Potassium ferrioxalate, also called potassium trisoxalatoferrate or potassium tris(oxalato)ferrate(III)[3] is a chemical compound with the formula K3[Fe(C2O4)3]. It often occurs as the trihydrate K3[Fe(C2O4)3]·3H2O. Both are crystalline compounds, lime green in colour.[4]
The compound is a salt consisting of ferrioxalate anions, [Fe(C2O4)3]3−, and potassium cations K+. The anion is a transition metal oxalate complex consisting of an iron atom in the +3 oxidation state and three bidentate oxalate C2O2−4 ligands. Potassium is a counterion, balancing the −3 charge of the complex. In solution, the salt dissociates to give the ferrioxalate anion, [Fe(C2O4)3]3−, which appears fluorescent green in color. The salt is available in anhydrous form[3] as well as a trihydrate.[5]
The ferrioxalate anion is quite stable in the dark, but it is decomposed by light and high-energy electromagnetic radiation.
