WebMetals are electron acceptors, and ligands are electron donors. There are two different types of ligands: weak field ligands and strong field ligands. Strong field ligands result in significant crystal field splitting and have a low spin value, whereas weak field ligands cause low crystal field splitting and have a high value. WebThe ligand field theory is a firm background to foresee the magnetic properties of metallic complexes ML n (M, transition metal ion; L, molecule or ligand). The ligand field splitting …
