Question
What is meant by didentate ligand?
Advertisements
Solution
A didentate ligand, also known as a bidentate ligand, is a ligand that can form coordination bonds to a metal ion using two donor atoms. These donor atoms are typically separated by a specific number of atoms in the ligand’s structure, forming a chelate complex.
