Crystal field theory explanation

WebCrystal field theory (CFT) is a bonding model that explains many properties of transition metals that cannot be explained using valence bond theory. In CFT, complex formation is assumed to be due to electrostatic interactions between a central metal ion and a set of negatively charged ligands or ligand dipoles arranged around the metal ion. WebOct 5, 2024 · In this section, we describe crystal field theory (CFT), a bonding model that describes the electronic structure of transition metal complexes, with an explicit focus on …
