WebJun 10, 2016 · By electronegativity, you would expect the nitrogen ligand to hold the metal's d electrons more strongly, but in the case of ammonia vs. phosphine based ligands, the phosphorus ligand has bigger p-orbitals, which have better overlap with the metal's d-orbitals, so the n M σ P ∗ interaction is stronger than n M σ N ∗. WebThe strong field ligands refer to the ligands that act as Lewis acids, which can donate electron pairs in both their ground and excited states. The Spectrochemical Series It is a …

WebJul 20, 2024 · NH3 is a ligand with medium field strength. This is because its sigma donating capability is not very strong, and more importantly, it is neither a pi acceptor non a pi donor. That is why NH3 ligand is located at middle of the “Spectrochemical Series” for ligand strength. In general, ligands are viewed as electron donors and the metals as electron acceptors, i.e., respectively, Lewis bases and Lewis acids. This description has been semi-quantified in many ways, e.g. ECW model. Bonding is often described using the formalisms of molecular orbital theory. Ligands and metal ions can be ordered in many ways; one ranking system focu…
WebSep 7, 2024 · According to Molecular Orbital theory of octahedral complexes, if the ligand is pi donor, it leads to decrease in crystal field splitting parameter (the same reason, why F- is a weak field ligand). This explains H2O being a strong field ligand than OH-.
