Ferrate or iron?

Postby Sarah Huang 3A » Thu Dec 03, 2020 1:20 am

When we are naming the coordination complexes, when do we know to use ferrate or iron(ate) for the naming of the metal?
I know ironate looks weird, but I saw it on a practice problem with a UA.

I'd really appreciate it if someone could explain this to me!

I think it's a nomenclature to use the Latin name(Ferrate) when naming a coordination compound.

how do you know which compounds are named with latin nomenclature and which ones are not.

I believe that it is called ferrate instead of something else because it has a +2 charge therefore it will end in -ate. I believe it is not called ironate due to it being defined, i.e. something we should memorize.

Ferrate was used at least by my TA when dealing with Iron. It is because it's the latin "ferra" and then the "-ate" at the end of the ion. I don't think it matters, but since -ferr was being used by my TA (and the UA in your case) I am assuming that is what is recommended.

My TA gave us some examples of when to use the Latin name for transition metals: Fe (ferrate), Cu (cuprate), Au (aurate). Looks like there's maybe a pattern here to use the Latin name when the atomic symbol isn't an exact abbreviation of its name?

Also, I think if the compound has an overall negative charge you add -ate to the end of the metal name. So this might play into the "ferrate" name.

Yeah I was actually wondering if ferrate would change if there is an overall positive charge or if it is called ferrate regardless of charge?
