A strong ligand or a strong field ligand is a ligand that can result in a higher crystal field splitting. This means, the binding of a strong field ligand causes a higher difference between the higher and lower energy level orbitals. Why are strong field ligands strong? Ions at the other end are known as weak-field ions.
