Prefixes
In lecture today Dr. Lavelle mentioned something about the prefixes bis-, tris-, tetrakis-, and pentakis-... can someone explain what he was talking about?

Re: Prefixes
I think he was saying that you use those to name the whole coordination compound if the polydentate ligand attached to a central metal atom already has a greek prefix (di-, tri-, etc) in its name.

Re: Prefixes
Can anyone provide an example of the naming with these prefixes? I would like to see how it's used.
Re: Prefixes
Bis- , tris- tetrakis-, pentakis- are used if the ligand has the same prefix as the polydentate so you wouldn't be using the prefix "di " twice to name a compound. The ligand would be named with di and then name the polydentate with "bis".

An example could be the compound ChloroBISethyleneDIaminecobalt(III)Sulfate. Because the ligand has the same prefix as the polydentate (di-), the second prefix, bis- is used.
