Naming complex ions

Postby Lauren Hekman 1A » Thu Nov 12, 2015 2:29 pm

When do you know when to use the suffix "bis" after an element? For example, chlorobis? Why wouldn't it be chloride?

If a ligand already has a prefix in the name, like ethylenediamine, then you must use the other prefixes if there is more than one ethylenediamine. For example, (en)2 is bisethylenediamine.

The "bis" in "chlorobis" is probably describing some other ligand rather than Cl. Also, you would use the "bis" and "tris" kind of prefixes for polydentate ligands as well.
