Overview of crystal field theory. According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being surrounded by an array of point ...

The d orbitals of a metal ion in an octahedral crystal field (surrounded by an octahedral array of ligands) are split into a higher energy eg set and a lower energy t2g set (Figure 1). This is due to electron clouds around each ligand (L) destabilizing those d-orbitals that lie along the X, Y, and Z axes.
