Naming

[Nikita Patra 3J]

When do we use the prefixes bis-, tris-, tetrakis-, etc.?

[Reina Robles 2B]

You use those when the ligand already contains a prefix (for example, (en)), is a polydentate, or it starts with a vowel.

I hope this helps!

[Diana Chavez-Carrillo 2L]

You use those when the ligand already contains a prefix (for example, (en)), is a polydentate, or it starts with a vowel.

I hope this helps!

Just to clarify, we only use prefixes for whats inside the brackets and not on the cation or anion outside the brackets correct?

[Bryce Ramirez 1J]

Yes you would only use it for the atoms that are inside the brackets in a complex.

Would we also use these prefixes if we were using oxalato?

[Shimei_2F]

use these when the ligand already has a prefix of bi- tri- tetra- etc.

[KHowe_1D]

You would use those when the ligand already has a prefix so for example en has a prefix already so if it was (en)2 it would be bisethylenediamine.

[Merin Padayatty 3G]

When the ligand already has a prefix, including polydentate ligands, you would use those prefixes.
