Polydentate = more than one lone pair?

Postby Julia Mazzucato 4D » Sat Nov 30, 2019 8:53 pm

I know that polydentate ligands must have more than one bonding site (and thus more than one lone pair), but do all ligands with more than one lone pair qualify as polydentate? How can you tell?

A polydentate ligand has more than two lone pair donating sites that are used to bond to a central atom.

Unidentates have only one lone pairs but anything with more than one will be considered a polydentate such as a bidentate ligands which have two lone pairs. The lone pairs can all bond to the central metal ion.

Can we determine the denticity (monodentate, bidentate, polydentate, etc.) of a ligand by simply looking at the coordination compound name? If so, how?

Polydentate ligands have two or more lone pair donating sites.
