More Information about the [Tris(catecholato)Iron(III)]3- Anion The Λ-[Tris(catechol)Iron(III)]3- Ion (showing multiple bonds but not illustrating the delocalized nature of the bonds) is presented on your left. Each ligand carries a 2- charge. Three 2- ligands coordinate to the Fe(III) ion to create a complex with overall charge of 3-. Reference for the Structure of the Λ Isomer: K.N.
