Is f a strong field ligand
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… WebCO ≈ CN − > strong-field ligands NO 2 − > en > NH 3 > SCN − > H 2 O > oxalate 2 − intermediate-field ligands > OH − > F > acetate − > Cl − > Br − > I − weak-field ligands. The values of Δ o listed in illustrate the effects of the charge on the metal ion, the principal quantum number of the metal, and the nature of the ligand.
