Crystal field theory notes
WebAug 15, 2024 · Crystal field theory (CFT) is a bonding model that explains many important properties of transition-metal complexes, including their colors, magnetism, structures, stability, and reactivity. The central assumption of CFT is that metal–ligand interactions are purely electrostatic in nature. Colors of Coordination Complexes WebThe crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal …

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.
WebApr 5, 2024 · Crystal field theory considers the central metal atom in a coordination complex as positively charged hard spheres. The metal atom has vacant orbitals to accommodate more electrons and hence is considered electron deficient. The groups surrounding the metal atom are called ligands.
