What is ligand field theory fundamentals?
Ligand Field Theory can be considered an extension of Crystal Field Theory such that all levels of covalent interactions can be incorporated into the model.
Treatment of the bonding in LFT is generally done using Molecular Orbital Theory.What is the CFT theory?
Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands.
CFT qualitatively describes the strength of the metal-ligand bonds.
Based on the strength of the metal-ligand bonds, the energy of the system is altered.Weak field ligands are ones that produce small splittings between the d orbitals and form high spin complexes.
Examples of weak field ligands include the halogens, OH- and H2O.
From a ligand field perspective these ions or molecules all have filled orbitals which can π bond with the metal d orbitals.
What is the ligand field theory?
ligand field theory, in chemistry, one of several theories that describe the electronic structure of coordination or complex compounds, notably transition metal complexes, which consist of a central metal atom surrounded by a group of electron-rich atoms or molecules called ligands.
