hi! could someone just quickly clarify why the end of [Co(NH3)5Cl]Cl2 isn't dichloride/ when that prefix would and wouldn't be used ? I think we used it in class for when there were 2 water molecules outside the brackets. thank you!

Hello!

I believe the reason for this is because Cl is not inside of the bracket, so it is not a ligand. Therefore, I believe it does not take a prefix as it is not a ligand but instead forms a bond with the positively charged portion of the coordination compound within the brackets. I hope this helps!

For anions outside the coordination sphere/bracket you would just use the normal anion name, but for specifically water that's when you add the greek prefixes. Hope this helps

Hi! This is because the Cl2 is outside of the coordination complex and therefore is just used as a way to counter act the overall oxidation state of the complex itself.

Based on the naming guidelines for ligands we should follow this order.
1. greek prefix
2. Ligand Name
3. Transition Metal
4. Oxidation state
5. Ions/atoms/molecules outside of the brackets
