Ligands

Postby Jessica Tejero 3L » Sat Dec 07, 2019 1:16 pm

This might be a dumb question but are polydenate ligands and bidenate ligands the same thing?

A bidentate is a polydentate because it binds to the central metal atom at two sites. Polydentates also include ligands that bind to the central metal atom at more than two sites.

They are both chelating ligands because they are complexes that contain a ligand that forms a ring of atoms around a central atom. The ring is formed because 2 electron pairs are donated for bidentate ligands. Polydentate ligands just have to donate more than one electron pair.

Bidentate is a form of polydentate. Polydentate can also refer to tridentate, tetradentate. Chelating are polydentate, but polydentate is not necessarily chelating.
