"WebWith weak-field ligands such as H2O, the ligand field splitting is less than the pairing energy, Δoct less than P, so the electrons occupy all d orbitals singly before any pairing occurs. In [Fe(H2O)6]2+, on the other hand, the weak field of the water molecules produces only a small crystal field splitting (Δoct < P). " - Crystal field splitting f orbitals

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. http://chemiris.labs.brocku.ca/~chemweb/courses/chem232/CHEM2P32_Lecture_10.html
