A general d-orbital splitting diagram for square planar (D 4h ) transition metal complexes can be derived from the general octahedral (O h ) splitting diagram, in which the d z 2 and the d x 2 − y 2 orbital s are degenerate and higher in energy than the degenerate set of d xy , d xz and d yz orbital s.

This causes a splitting in the energy levels of the d-orbitals. This is known as crystal field splitting. For octahedral complexes, crystal ...6 May 2021 · Uploaded by Chuck Wight

This effect is particularly evident in d 9 configurations. The configuration in a octahedral complex would be t 2g 6 e g 3, where the configuration has degeneracy because the ninth electron can occupy either orbital in the e g set. A tetragonal distortion removes the degeneracy, with the electron of highest energy occupying the non degenerate d x 2 - y 2 orbital.

We rationalize this by saying there are no d orbitals close in energy to the valence 2s and 2p orbitals (2d orbitals are forbidden energy levels).

It is important to note that the splitting of the d orbitals in a crystal field does not change the total energy of the five d orbitals: the two e g orbitals increase in energy by 0.6Δ o, whereas the three t 2g orbitals decrease in energy by 0.4Δ o. Thus the total change in energy is. (1.2.1) 2 ( 0.6 Δ o) + 3 ( − 0.4 Δ o) = 0.
