High spin komplex

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 l A 1g, … WebSep 7, 2024 · However, as a general rule of thumb, most 3d metal complexes are high-spin. If you return to the fundamental criterion for high- vs low-spin, i.e. the relative magnitudes of Δ o and the pairing energy, you will find that for many 3d metals, Δ o is small due to the poor overlap of the 3d orbitals with ligand orbitals.
