Polydentate

[Artin Allahverdian 2H]

How can we tell if a ligand is polydentate so that we know whether to use bis-, tris-, tetrakis-, etc?

[Krisdylle Repollo 4H]

If the ligand has more than one binding site, then it is considered a polydentate.

[Daniel Bowen 3I]

So would anything that is not a monodentate be considered polydentate?

[Joaquin Andrade]

If a ligand can bond to the central metal atom with two atoms, it is bidentate. For three atoms, it is tridentate. For any more, the term polydentate is typically used.

[Tyler Vu 4I]

Ligands with more than one bonded atom (central metal atom) are considered polydentate. The prefixes mentioned are used with composite ligand names to avoid confusion.

[KHuang1L]

In the ligand worksheet that is on the class website, remember that ox, en, dien, and edta are all polydentate. So you would use bis and tris instead of bi and tri.

Would carbonato also be considered a polydentate then?

[yaosamantha4F]

I believe carbonato is bidentate!

[Rehan Chinoy 1K]

It's also helpful to see if the molecule has nitrogen, oxygen, or sulfur atoms with lone pairs because these are common binding sites for ligands and thus would make the molecule polydentate.

[Alexa_Henrie_1I]

Is dien tridentate or tetradentate?

[605168557]

based on the amount of bonding sites to the single central atom

[Abby-Hile-1F]

How do you specify if a ligand is polydentate when naming the compound?
