Web3 de jun. de 2024 · 3d complexes are high spin with weak field ligands and low spin with strong field ligands. High valent 3d complexes (e.g., Co 3+ complexes) tend to be low … 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…

WebOverview of crystal field theory. 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 … The spectrochemical series was first proposed in 1938 based on the results of absorption spectra of cobalt complexes. A partial spectrochemical series listing of ligands from small Δ to large Δ is given below. (For a table, see the ligand page.)
