More Information
Octahedral complexes are coordination complexes formed between a central metal atom and six ligands arranged at the vertices of an octahedron. The electronic configuration of the metal ion and the nature of the ligands influence the magnetic properties of these complexes. Strong-field ligands cause a large splitting of the d-orbitals, leading to low-spin complexes which tend to be diamagnetic. Weak-field ligands cause a smaller splitting, resulting in high-spin complexes which are typically paramagnetic.
Tips
It's easy to confuse the magnetic properties of strong-field and weak-field complexes. Always remember that strong-field ligands usually result in diamagnetic complexes due to pairing of electrons, while weak-field ligands usually result in paramagnetic complexes due to unpaired electrons.
