High field ligands
WebIntroduction:- Spectrochemical series is a list of ligands arranged in order of their field strength. The ligands cyanide and co are considered as strong field ligands and the halides are weak field ligands. Ligands such as water (h2o) and ammonia (nh3) are medium field ligand. The spectrochemical series places ligands in order of increasing (Δ). http://chemwhite.com/what-is-spectrochemical-series-weak-field-ligand-and-strong-field-ligand/

Web16 de abr. de 2024 · Halogens still act as weak-field ligands even in the case of square planar $\ce{[PtCl4]^2-}$ complexes. Weak field does not automatically mean high spin and neither does strong field automatically mean low spin.. Whether a complex adopts a high or a low spin state depends on the central metal’s oxidation state, its position in the periodic …

According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being …

CFT describes certain properties of coordination complexes but is …
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 …
