Question
What is crystal field splitting energy?
Solution
1. In an octahedral complex, the d-orbitals of the central metal ion divide into two sets of different energies. The separation in energy is the crystal field splitting energy.
2. The d-orbitals lying along the axes dx2, dy2 and dz2 orbitals will experience strong repulsion and raise in energy to a greater extent than the orbitals with lobes directed between the axes (dxy, dyz and dzx). Thus the degenerate d-orbitals now split into two sets and the process is called crystal filled splitting.
