As we discussed in concept

Weak field Ligand -

These are the ligands which do not pair the electron in inner d-orbital.

- wherein

For example: N_{2}O, F^{-}, Cl^{-} etc    

 

 Ion with 4d^8\: and \:5d^8 configuration form square planer complex with all type of ligand.

\left [ PtCl_4 \right ]^{2-}is a square planer complex.
