High and low field ligands
WebIron(II) has the 3d 6 outer electronic configuration and hence its octahedral complexes may be either high-spin or low-spin. The high-spin configuration, t 4 2g e 2 g, is adopted when relatively weak-field ligands are coordinated while the low-spin, t 6 2g e 0 g, is obtained when strong-field ligands are involved.In Oh symmetry the ground states are 5 T 2g and … Web11 de out. de 2024 · Strong-field ligands refer to ligands that act ...

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… The spectrochemical series was first proposed in 1938 based on the results of absorption spectra of cobalt complexes.
