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. Ligands come in, and their important orbitals interact with the metal d orbitals. Electrons repel electrons to destabilize certain metal d orbitals. In an octahedral field, these are known as the e* g … 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 … 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. things interesting

If the ligands attached to the Fe (II) metal are strong-field ligands in an octahedral configuration, a low-spin situation is created in the d orbitals. 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.

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.
