Chelating

[Kati Rady-Pentek 1E]

How do you know if a ligand will chelate with the metal?

Ligands need two or more points (Bidentante or more) to bind to the central TM to form a chelating complex.

[Darren Apostol 2L]

As said, if there's a ligand that bonds to the central metal at two or more points, the compound is a chelate. An example is en or ethylenediamine which is bidentate (the two nitrogens have lone pairs).

[Shania Garrison Discussion 3E]

helating happens when you you have a polydentate ligand. Chelating means that it must form a ring around the transition metal. This can be on big molecule like a hexadentate one, or something like 2 bidentate molecules

[Mahika Saoji 3K]

Hi! A chelate by definition is a ligand that is bonded to a central metal atom at two or more points. Chelating usually occurs when you have a polydentate ligand. I hope that helped!

In lecture, professor said that a simple rule is if there is an atom with an atom with a lone pair bound to a spacer that is bound to another spacer that is bound you an atom with a lone pair you can have a chelate. Simply: Atom with a lone pair--spacer--spacer--atom with a lone pair, where the -- are bonds and the spacers are atoms (like C).
