EDTA and Bonding Sites

Postby Kathleen Vidanes 1E » Sun Nov 26, 2017 11:31 pm

Can someone please explain how EDTA has 6 bonding sites? Thank you.

EDTA is a ligate, so it has 4 binding sites with oxygen and 2 binding sites with nitrogen.

What exactly is a ligate?

I believe the former response meant to say "polydentate," which essentially means that the ligand can bond to two or more bonding sites simultaneously. EDTA has six bonding sites making it a hexadentate ligand; it can bond at up to six bonding sites simultaneously.

This is of great importance, especially when considering the determination of the coordination number!

Hope that helps!

The above answers are correct, but Vincent probably meant ligand, not ligate!

Oops, I'm sorry I meant ligand.
