WebAccording to crystal field theory, a transition metal with no bound ligands has five d- orbitals that are degenerate, or equal in energy. Binding a ligand to the metal “splits” the d- orbitals and causes some orbitals to be higher in energy than the others. This is known as crystal field splitting 1.
WebCrystal field theory treats interactions between the electrons on the metal and the ligands as a simple electrostatic effect. The presence of the ligands near the metal ion changes the energies of the metal d orbitals relative to their energies in the free ion. Both the color and the magnetic properties of a complex can be attributed to this ...
