WebThe high-spin state of a metal ion always contains more electrons in metal-ligand antibonding d-orbitals (the e g subshell in Scheme 1), leading to weaker M‒L bonds and … 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… WebStrong-field ligands, such as CN − and CO, increase the Δ splitting and are more likely to be low-spin.
