http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch12/crystal.php The six bonding molecular orbitals that are formed are "filled" with the electrons from the ligands, and electrons from the d-orbitals of the metal ion occupy the non-bonding and, in some cases, anti-bonding MOs. The energy difference between the latter two types of MOs is called ΔO (O stands for octahedral) and is determined by the nature of the π-interaction between the ligand orbitals with the d-orbitals on the central atom. As described above, π-donor ligands lead to a s…

WebSome ligands are 'weak' but will form strong ligand fields with certain metals in certain oxidation states. Co 2+ will behave more like other metals on the table and form a high spin complex with oxalate. (C2O4)2- is a weak field ligand but due to chelation it behave as strong field ligand. It's not because of chelation effect. 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.
