Crystal Field Splitting in an Octahedral Field - IIT Kanpur

WebWeak field ligands: Weak field ligands are those ligands that can not pair the valence electrons of a metal ion. Normally, Aqua (H2O) is considered a weak field ligand. But in the case of the metal ion having an oxidation state +3 or higher than +3 and transition metals of 4d and 5d series, H2O acts as a strong ligand. Suggest Corrections. WebEach ligand has at least one orbital containing a lone pair of electrons. Pauling classified the ligands into two categories (i) Strong ligands like CN –, CO – etc. (ii) weak ligands like F –, Cl – etc. 5. Strong ligands have a tendency to pair up the d-electrons of a metal cation or atom to provide the necessary orbitals for hybridization.
