Coordination Numbers

Postby Alexis Elliott 1J » Mon Nov 14, 2016 7:34 pm

So coordination numbers are the number of places a ligand can mind to a metal cation I think. Dr. Lavelle said in lecture that ethylenediamine can bind in 2 places and diethylenetriammine can bind in 3. However, I am having difficulty figuring out how many places nitrito, carbonato, oxalate,sulfato and EDTA can bind in. Is there an general rule one can follow to figure out the number of places one of these ligands can bind to? If not, does anyone know how many places those compounds can bind at?

Thanks!!

nitrito--> 1 carbanato--> 1 sulfato---> 1 edta--> 4

I know that for EDTA it binds 4 times because it has 4 ends where the oxygens are bent, which makes it easier for chelating to occur.

What about oxalato? Is it one also?

Oxalato is 2 because it is bidentate
