Explain the following term with an example: Hexadentate ligands.

(N/A) Hexadentate ligands: These are ligands that possess $six$ donor atoms and are capable of forming $six$ coordinate bonds with a single metal ion simultaneously.
Example: Ethylenediamine tetraacetate $(EDTA^{4-})$ is a classic example of a hexadentate ligand. It contains $two$ nitrogen atoms and $four$ oxygen atoms as donor sites,as shown in the structure:
