What is the Nephelauxetic Series for Ligands ?

The list shown below enlists some common ligands (showing increasing nephelauxetic effect , in order of increase of the amount of renormalization):

F− > H2O > NH3 > ethylenediammine > [NCS - N]− > Cl− > [CN]− > Br− > N3− > I−

What is the Nephelauxetic Series for Metals?

The nephelauxetic effect does not only depend upon the ligand type, but also upon the central metal ion. These too can be arranged in order of increasing nephelauxetic effect as follows:

Mn(II) < Ni(II) ≈ Co(II) < Mo(II) < Re(IV) < Fe(III) < Ir(III) < Co(III) < Mn(IV)
