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, … 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 complexes, in particular optical spectra (colors). CFT successfully accounts for some magnetic properties, colors, hydration enthalpies, and spinel structures of transition metal complex… earliest human ancestor

The value of 10 D q even depends strongly on the geometry: octahedral complexes have a much larger value of 10 D q than tetrahedral ones: 4.44 D q ( oct) ≈ 10 D q ( tet) The notation does not extend well to complexes in geometries other than octahedral or tetrahedral. WebThe crystal field theory (CFT) was developed for crystalline solids by the physicist Hans Bethe in 1929. The model takes into account the distance separating the positively and negatively charged ions and treats the ions simply as point charges with the attractive and repulsive interactions between them as purely electrostatic/ionic ones.
