According to C.F.T, attraction between the central metal ion and ligands in a complex is purely electrostatic. The transition metal which forms the central atom cation in the complex is regarded as a positive ion. It is surrounded by negative ligands or neutral molecules which have a lone apir of electrons, if the ligand is a neutral molecule such as NH_(3) , the negative and of the dipole in the molecule is directed towards the metal cation. the electrons on the central metal ion are under repulsive forces from those on the ligands. thus the electrons occupy the d-orbitals remain away from the direction of approach ligands. ltBrgt Q.

The increasing order of the crystal field splitting power of some common ligands is

The crystal field splitting energy for octahedral (Delta_(0)) and tetrahedral (Delta_(t)) complexes is related as .

The crystal field stabilisation energy of [Co(NH_(3))_(6)]Cl_(3) is:

The magnitude of crystal field stabilisation energy in octaheral field depends on: (I) the nature of the ligand (II) the charge on the metal ion. (III) whether the metal is in the first, second or third row of the transition elements

In which structure crystal field splitting energey (CFSE) for octahedral complex will be zero when DeltaltP .

On the basis of crystal field theory explain why Co(III) Forms paramagnetic octahedral complex with weak field ligands whereas it forms diamagnetic octahedral complex with strong field ligands.
