Polydentate v. Chelate

Postby aisteles1G » Sat Dec 08, 2018 10:37 am

Im a little confused on if polyedentate means the molecule can form multiple bonds with different metal atoms or just with the same metal atom? As far as I understand chelating means forming the multiple bonds with the same central atom but does polydentate just mean the same thing then? Thanks!

You have the right idea. Polydentate means one ligand can bind to the same metal atom at different binding sites. The chelate is the complex that is produced when a polydentate ligand binds to a metal atom and forms a ring. Chelation is just this process, and the polydentate ligand can be referred to as the chelating agent.
