Ligand use -ate

Postby 505612629 » Sun Dec 13, 2020 10:38 am

when do we put -ate at the end of naming a ligand?

You use -ate when your anion itself is the ligand

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

I agree with Andrew! ^^ I think Dr. Lavelle mentioned in lecture that it's when the coordination sphere is negative

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

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

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.

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

You ate when the ligand has a negative charge on the outside of the brackets.

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.

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!

When the entire coordination compound (the stuff inside the square brackets) is negatively charged.

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

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.

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.

Hi! -ate is used when there is an overall negative charge

Hi! You would use "-ate" at the end of a metal name if it is an anion complex.
