9.15     Discuss the nature of bonding in the following coordination entities on the basis of valence bond theory:

                  (i)[Fe(CN)_{6}]^{4-}

                

Answers (1)

In the given compound oxidation state of Fe is +2. The electronic configuration of this compound is 3d6.

Also CN- is a strong field ligand so it will cause the pairing of electrons.

                                           

Therefore the complex is diamagnetic and its geometry is octahedral.
