What is Ligand Field Theory?
A more complete version of crystal field theory that considers the covalent character of metal-ligand bonds. It uses molecular orbital theory to explain the electronic structure of coordination compounds, including their spectral and magnetic properties.

LFT explains: why CO and CN⁻ are strong field ligands (π-backbonding from metal to ligand vacant π* orbitals), why metal carbonyls have low oxidation state metals (π-acceptor stabilisation of low-valent metals), magnetic properties, colour, and reactivity of coordination compounds. It is used in the…
No direct safety concern for the theory. Ligand field concepts help predict complex stability and potential ligand release — important for understanding whether toxic ligands (CO, CN⁻) will dissociate from metal complexes under physiological conditions.
