Those ligands which cause larger splitting of d orbitals and favour pairing of electrons are called strong field ligands. Being lewis basesthose who donate electrons the ligands with less electronegativity will be stronger. Ligands that bind through N are intermediate in strength.
Also know is EDTA a strong ligand. In coordination chemistry a pi-donor ligand is a kind of ligand endowed with filled non-bonding orbitals that overlap with metal-based orbitals. The strong field is a low spin complex while the weak field is a high spin complex. EDTA is a moderately strong field while en is a strong field ligand. CN NCS CO NH 3 EDTA en ethylenediammine. These properties are often defined in the spectrochemical series of ligands which ranks them from weak to strong where stronger ligands are associated with a larger energy difference.
The strong field is a low spin complex while the weak field is a high spin complex.
The magnitude of Δ o is determined by the field-strength of the ligand. Donors as anionic ligands.

Therefore in general halogen or oxygen donors eg-F-Cl-Br-H2Oare weak field ligands and the ones in which carbon or nitrogen atom is the donor eg-CN-CONH3 are strong field ligands. Strong field ligands contain C N and P as donor atoms. EDTA 4-is classified as an L 2 X 4 ligand features four anions and two neutral donor sites.
