High and low field ligands
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 … Web8 de set. de 2024 · 1.3: Spectrochemical Series. Another factor that plays a key role in whether a transition metal complex is high- or low-spin is the nature of the ligands. The …
