WebA weak ligand or a weak field ligand is a ligand that can result in a lower crystal field splitting. This means, the binding of a weak field ligand causes a lower difference … WebLigands which cause a large splitting Δ of the d -orbitals are referred to as strong-field ligands, such as CN − and CO from the spectrochemical series.
