WebLigands like CO, CN-, and NH3 form low spin complexes. NO2- forms high spin complexes. Ligands forming low spin complexes can split the d-orbitals by more extent than that of high spin complexes. The low spin complex forming ligands are also called strong field ligands and the high spin complex forming ligands are called low field … WebHigh Spin and Low Spin Electron configurations for octahedral complexes, e.g. [M(H2O)6]n+.

Crystal field theory - Wikipedia

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… Web23 de nov. de 2024 · Examples of low-spin d6 complexes are [Cr(CN)6]3− and Cr(CO)6, and examples of high-spin d6 complexes are [CrCl6]3− and Cr(H2O)6.

WebStrong-field ligands, such as CN − and CO, increase the Δ splitting and are more likely to be low-spin. Weak-field ligands, such as I − and Br − cause a smaller Δ splitting and are more likely to be high-spin. Some octahedral complexes exhibit spin crossover, where the high and low spin states exist is dynamic equilibrium.
