Main Question or Discussion Point

As per IUPAC Nomenclature of Inorganic Chemistry, the correct name of the edta chelate is $$\text{2,2′,2″,2′″-(ethane-1,2-diyldinitrilo-} κ^2 \text{N)tetraacetato-}κ^4O $$ As far as I know, edta coordinates through Nitrogen and Oxygen atoms, and there is no metal-carbon bond.

On the other hand, the "yl" in the name indicates a metal-carbon bond, because the "yl" or "ido" suffixes are for organometallic compounds. For example, the complex ##[Ti(CH_2 CH_2 CH_3) Cl_3] ## compund is named ##\text{trichlorido(propan-1-yl)titanium}## as per the organometallic nomenclature system.

Then why has the "yl" suffix been used in edta?
