Question

Is glycinato a bidentate ligand?

Answer 1

1. Bidentate ligands are those which can donate two pairs of electrons to a central metal atom.
2. Glycinato is a bidentate ligand because it is formed with two groups one is the amino$\left(\mathbf{-}{\mathbf{NH}}_{\mathbf{2}}\right)$ group and the other is a carboxylate ion group$\left(\mathbf{-}{\mathbf{COO}}^{\mathbf{-}}\right)$.
3. The structure of glycinato is given as-

As in the above structure, it is clear that glycinato has two donor atoms oxygen and nitrogen and both can donate their electrons hence it is a bidentate ligand.

Hence, Glycinato is a bidentate ligand.
