chelates

Postby Jackie Ngo 1C » Sun Dec 02, 2018 11:52 pm

do chelates have a distinct shape? or do they just need to have the basis of a central atom?

Chelates do need to have a specific shape, cyclic or ring structure. For example, in an ethylenediamine-cadmium complex, a chelate ring occurs.

I believe chelates are ring-shaped with the metal ion in the middle surrounded by ligands in the coordination sphere.

Can there be multiple rings around the same central atom?

Yes, like having 3 bidentates around one metal.
For example, you can have 3 (en) ligands around a Co, with each forming its own ring around the Co.

Chelates are in the shape of rings, making them pretty easy to distinguish.
