"WebOct 11, 2024 · A strong ligand or a strong field ligand is a ligand that can lead to a higher crystalline field cleavage. This means that binding a strong field ligand causes a higher difference between the higher and lower energy level orbitals. Examples are CN– (cyanide ligands), NO2– (nitroligand) and CO (carbonyl ligands). " - Strong field ligand list

WebLigands and metal ions can be ordered in many ways; one ranking system focuses on ligand 'hardness' (see also hard/soft acid/base theory). Metal ions preferentially bind certain ligands. In general, 'soft' metal ions prefer weak field ligands, whereas 'hard' metal ions prefer strong field ligands. 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.
