Example of chelating ligand
WebThe most common examples of this type of ligand are ethylenediamine (en), oxalate (ox). These ligands are named as ‘bi’ as they tend to give two pairs of electrons to the metal atom or ion at the center. These ligands are also referred to as chelating ligands.

WebApr 6, 2024 · This means the binding of a strong field ligand causes a higher difference between the higher and lower energy level orbitals. Examples include CN– (cyanide ligands), NO2– (nitro ligand) and CO (carbonyl ligands). A weak ligand or a weak field ligand is a ligand that can result in a lower crystal field splitting. In the 1960s, scientists developed the concept of chelating a metal ion prior to feeding the element to the animal. They believed that this would create a neutral compound, protecting the mineral from being complexed with insoluble salts within the stomach, which would render the metal unavailable for absorption. Amino acids, being effective metal binders, were chosen as the prospective ligands, and research was conducted on the metal–amino acid combinations. The r…
