Multiple metal-ligand binding sites

Chelation The complexation of a metal cation by an organic ligand. Some ligands have multiple binding sites. Those with two sites are called bidentate ligands. 

Scheme 1.3 Equilibrium constants (K) for multiple ligands (L) binding to a single metal (M) via a binding site on the ligand termed A interacting with a binding site on the metal termed B .

For simple processes in which multiple metals bind to a single ligand = 1 and iEL = 1 (AEE1 = 0) and hence the extended site binding model reduces back the basic site binding model. Figure 10.17 shows...
