Hexammineferric
Hexammineferric, also known as trioxalatoferrate(III) or ferric oxalate complex, is an inorganic compound with the chemical formula [Fe(C2O4)3]3-. It is a coordination complex where a central iron(III) ion is coordinated to three oxalate ligands. Oxalate (C2O4^2-) is a bidentate ligand, meaning each oxalate ion binds to the iron atom through two oxygen atoms. The overall charge of the complex ion is -3, and it is typically balanced by a cation, such as potassium or sodium, to form a neutral salt.
Hexammineferric compounds are often crystalline solids and can vary in color depending on the specific cation
The synthesis of hexammineferric compounds usually involves reacting an iron(III) salt with an oxalate salt in
