Prefix bis, tris, tetrakis, etc. [ENDORSED]

[Tam To 1B]

Hello!

I'm a little confused as to when we name coordination compounds with bis, tris, tetrakis, etc.
What's an example of when this is used instead of di, tri, tetra, etc.?

Thank you!

You would use this if the compound contains a ligand that has bi- tri- etc. in the name to avoid confusion. For example, palladium (0) tetrakis(triphenylphosphine).

Di-, tri-, and tetra- should be used for multiple monodentate ligands while bis-, tris-, tetrakis- would be used for for multiple polydentate ligands.

[Manya Kidambi 3I]

An example of this - if you had (en)3 (ethylenediamine) for example, it would be tris-ethylenediamine.

Di-, tri-, and tetra- should be used for multiple monodentate ligands while bis-, tris-, tetrakis- would be used for for multiple polydentate ligands.

What is a monodentate ligand and what's a polydentate ligand? I don't understand the difference.

Monodentate ligands have one e- donor to bind with another central atom, but bidentate has 2 e- donor, etc...
