WebSep 2, 2015 · metal to ligand π-backbonding can take place. Especially that final point is important. Ammonia is very bad at π backbonding (and amide is even π-donating). So calling it a high-field ligand is misappreciating physicochemical reality. It is just ammonia’s strong σ bonding ability that causes a slightly larger field split than water. WebApr 8, 2024 · The most common simple ligands are oxygen, nitrogen, halogens, carbon monoxide and water. The complex ligands are those that bind to the metal ion through a pair of donor atoms or a donor atom and a lone electron pair. The most common examples for this type of ligand include ethylene dibromide (EDB) and nitriles.
