WebSep 5, 2024 · To see that this makes sense, you can think about crystal field splitting as an electrostatics problem. The orbital has to pay an energy penalty if it points towards another ion with other electrons present. Hence the orbitals that point "between" nearby ligands have the lowest energy.
