Crystal-field theory

Crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, usually d or f orbitals, due to a static electric field produced by a surrounding charge distribution (anion neighbors). This theory has been used to describe various spectroscopies of transition metal coordination … See more 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 … See more The crystal field stabilization energy (CFSE) is the stability that results from placing a transition metal ion in the crystal field generated by a set of ligands.

Crystal Field Theory -- from Eric Weisstein

WebAccording to crystal field theory, a transition metal with no bound ligands has five d- orbitals that are degenerate, or equal in energy. Binding a ligand to the metal “splits” the d- orbitals and causes some orbitals to be higher in energy than the others. This is known as crystal field splitting 1. WebCrystal field theory was developed by considering two compounds: manganese (II) oxide, MnO, and copper (I) chloride, CuCl. Octahedral Crystal Fields Each Mn 2+ ion in manganese (II) oxide is surrounded by …
