Crystal field splitting f orbitals
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 charges consisting of the ligands. … WebWith weak-field ligands such as H 2 O, the ligand field splitting is less than the pairing energy, Δ oct less than P, so the electrons occupy all d orbitals singly before any pairing …
