Re: Ligand use -ate
From Dr. Lavelle's lecture it's when the coordination sphere is overall negative, for example [Ni(CN)4]^-2 is tetracyanonickelate (II).

Re: Ligand use -ate
I agree with Andrew! ^^ I think Dr. Lavelle mentioned in lecture that it's when the coordination sphere is negative

Re: Ligand use -ate
You add -ate to the end of the name of the central metal atom when the overall charge of the compound is negative.

Re: Ligand use -ate
-ate should be added to the metal that ligands are connecting to if the outcome of the molecule (in the brackets) are negative.

Re: Ligand use -ate
Hi! "-ate" is added to the end of the ligand name when there is a negative charge associated with what's in the square brackets.

Re: Ligand use -ate
You would use -ate for the transition metal when the charge of the coordination sphere has a negative charge

Re: Ligand use -ate
You add -ate to the transition metal name when the compound in the brackets has an overall negative charge. Lavelle said this doesn't happen super often so the point is to make the name sound strange so that we are aware that it is different and negative.

Re: Ligand use -ate
I'm a little late but this question was a good review for me moving on to other chemistry classes so thanks! Lavelle said in a lecture that when the coordination sphere is overall negative you add the -ate to the end of the TM name!

Re: Ligand use -ate
When the entire coordination compound (the stuff inside the square brackets) is negatively charged.

Re: Ligand use -ate
you use the suffix -ate when the entire ligand has a negative charge (is an anion).

Re: Ligand use -ate
The suffix -ate is used in the case that the whole complex of the coordination compound is actually negative. Therefore, its anions and hence it will commonly be found at the end of a compound. I say this because the anions are followed after cations. For example Na Cl- therefore, cations than anions. That's a tip. Other than that, the overall charge is negative it's ate.

Re: Ligand use -ate
You would use the suffix -ate when the coordinate compound is acting as the anion when interacting with a cation. So, instead of just having the metal name and then the charge, you would add -ate (like nickelate) at the end of the metal name to help indicate that it is acting as the anion.
