ironII110phenanthroline
Iron(II) 1,10-phenanthroline, often abbreviated as Fe(phen)3(2+), is a coordination complex consisting of an iron(II) ion coordinated to three bidentate 1,10-phenanthroline ligands. 1,10-phenanthroline is a heterocyclic organic compound with a planar structure containing two fused pyridine rings. This tridentate coordination to the central iron ion forms a stable octahedral complex.
The complex is well-known for its intense red color, which arises from metal-to-ligand charge transfer (MLCT)
Fe(phen)3(2+) exhibits notable electrochemical properties and can undergo redox reactions. It is also a relatively robust
