Naming Carbon Dioxide as a Ligand

[Maham Kazmi 2J]

Hey! I remember learning that with polyatomic molecules, we use "“bis, tris, tetrakis & pentakis” since "di, tri" are already used and this would be repetitive. So for example, 2 diethylene triamine ligands would be called bis diethylenetriamine.

I was confused, however, on what we would call 2 carbon dioxide as a ligand since the "di" isn't in the beginning of the molecular name. Would it be bis carbon dioxide?

Sorry if this question is a bit confusing but I'd love clarification! Thank you!

Hi!

I think that it would be bis carbon dioxide as in lecture Dr. Lavelle, said that if the ligand has a name that already includes di, tri, tetra etc., then we use the prefixes bis, tris, tetrakis, and so on. I don't think it has to be at the beginning of the name. Hope this helps!
