chelating complexes

Postby Katie Bart 1I » Sun Nov 24, 2019 5:16 pm

How do you know if a molecule is going to be chelating based off of its lewis structure?

We can predict if a polydentate ligand has the ability to form chelates based on the bonds it has within itself. For example, the NH2-CH2-CH2-NH2 ligand was able to form a chelate with a cation metal because the bonds within that ligand composed of only sigma bonds, which allow rotation into a ring configuration that allows binding at two sites on the TM cation, forming a chelate.

Does that mean that any polydentate ligand has the ability to form chelates if it can rotate into a ring configuration that allows binding at more than one site?
