Crystal field theory explanation
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. WebNi2+, in the presence of strong field ligands such as CN-forms a square planar complex. 2nd and 3rd row d8 metals form square planar geometry irrespective of the nature of the ligand: With Pd2+ (which already generates a strong field) even a weak field ligand such as Cl-leads to the formation of a square planar complex, for example, [PdCl 4] 2-.
