Crystal filed theory

WebThe Crystal Field Theory (CFT) is a model for the bonding interaction between transition metals and ligands. It describes the effect of the attraction between the positive charge of the metal cation and negative charge on the non-bonding electrons of the ligand. WebMay 12, 2015 · No two complexes will have exactly the same value for 10 D q. 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.

WebJUST A SHORT WebThe crystal field theory (CFT) was introduced by Hans Bethe and J.H Van Vleck around 1930. CFT is based on the principle that the forces of attraction between a metal ion and the ligands present in a transition metal complex are purely electrostatic (100 % ionic).
