Naming Coordination Compounds

Postby Julia_Gordon_2A » Sat Dec 03, 2016 4:05 pm

When do we need to use "bis" and "tris" etc in naming coordination compounds and how do they differ from "di" "tri" etc..?

If a molecule is polydentate ie: en, dien, or oxalato, you use bis and tris for the amount of that molecule.

ex: Na3[Co(C2O4)3] would be sodium tris(oxalato) cobaltate III

You use di and tri with non-polydentate molecules (most other ligands we learned).

If there is already a prefix in the name of the ligand (for example, ethylenediamine) and you have 2 or more of that in your coordination compound, you would use bis, tris, etc. to indicate that.
