(N/A) Pentadentate ligands: These are ligands that possess five donor atoms and form five coordinate bonds with a central metal ion.
Example: Ethylene diamine triacetate $(EDTA^{3-})$. The structure shows five donor sites (three oxygen atoms from carboxylate groups and two nitrogen atoms from amine groups) capable of coordinating with a metal ion.
