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. … WebApr 6, 2024 · The crystal field theory is a model that explains the observed physical and chemical properties of transition metal complexes. It is based on the idea that when transition metals form complexes, the ligands (atoms or molecules) that are bonded to the metal interact with the metal's d orbitals.

WebJul 13, 2024 · In most coordination environments, the crystal field splitting is small compared to the energy necessary to cause spin pairing of electrons. This means that if five electrons are present in an octahedrally coordinated cation, three will occupy the t 2g and two the e g -level (Fig. 2 ).
