Chelating Ligands

Postby Jada Brown 2H » Sun Nov 24, 2019 11:27 am

Can someone explain chelating ligands/how they work? Will we need to be able to recognize them when looking at a structure?

Basically, a chelating ligand is one that can bond multiple times to the central metal ion by forming a ring with it. This is a result of the ability to rotate about sigma bonds so that the ligand can conform its shape to create that structure.

Chelating ligands can bind cations tightly. Therefore, the larger the number of ring closures to a transition metal, the more stable the compound is.

Chelating ligands are flexible molecules that have sigma bonds and can form multiple coordination compounds with the same transition metal. This makes them especially strong.
