Crystal field theory explanation
WebLigand-field theory is more powerful than either the valence-bond or crystal-field theories. Unfortunately it is also more abstract. The ligand-field model for an octahedral transition-metal complex such as the Co(NH 3) … WebThe crystal field theory was proposed by Hans Bethe and VanVleck. This theory gives satisfactory explanation for the bonding and the properties of complexes than the valence bond theory. Assumptions of Crystal field theory: The interaction between the metal ion and the ligand is purely electrostatic.
