It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals. CFT focuses on the nonbonding electrons on the central metal ion in coordination complexes not on the metal-ligand bonds.

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.
WebThe following points will clearly state the limitations of crystal field theory: The assumption that the interaction between metal-ligand is purely electrostatic cannot be said to be very realistic. This theory takes only d-orbitals of a central atom into account. The s and p orbits are not considered for the study.
