Is Carbonate bicarbonato or bis(carbonato)

Postby 704320688 » Mon Nov 18, 2013 12:32 am

As a ligand is carbonate bicarbonato or bis(carbonato). I think it is the latter because it is a bidentate but I am not sure? Can someone verify or correct me?

When are there 2 carbonates, you say -dicarbonato-.

You only use bis- when there is already a di- or tri- in the molecule itself, such as ethylenediamine. To denote two of those, you would say bisethylenediamine to avoid confusion.

But carbonate is a bidentate and when you have bi/polydentates, the book says to use bis- tris- tetrakis-

CR page 122 says "If ligand has name with DI-, TRI-, TETRA- then use prefixes BIS-,TRIS-,TETRAKIS-.

I asked a UA this question, and they said to use the bis-, tris-, etc... prefixes whenever a compound is polydentate. If there is a "di" or "tri" in the molecule, that's a dead giveaway to use the other prefixes, but this rule isn't restricted to just those.

Therefore, YES, it would be biscarbonato.
