Crystal field theory explains metal complex color, magnetism, and stability through d-orbital splitting in ligand field.
Trinn-for-trinn guide
- 1Input metal ion, ligands, geometry
- 2Calculate d-orbital splitting energies
- 3Predict color and magnetic properties
Løste eksempler
Inndata
[Fe(CN)₆]⁴⁻: strong field, low spin, diamagnetic
Resultat
vs. [Fe(H₂O)₆]²⁺: weak field, high spin, paramagnetic
Vanlige feil å unngå
- ✕Confusing high vs. low spin
- ✕Not applying to correct geometry
Ofte stilte spørsmål
Why does color depend on coordination?
Different ligand fields cause different d-orbital splittings; visible light absorption matches energy gaps.
