When do we refer to iron as "ferrate" in the coordination compound name, and when do we use "iron"? I've seen it in the textbook both ways but I'm not sure when to do which. Thank you so much!
I think we always use ferrate for coordination compounds.
Yes, it is when naming coordination compounds. My TA also had in my discussion section that, "for some metals, the Latin names are used in the complex anions (e.g. Fe is called ferrate, not ironate)."
To clarify, we use the latin names with suffix -ate if the complex ion is an anion. So for K4[Fe(CN)6], the overall charge of the complex ion is 4-, therefore this would be potassium hexacyanoferrate(II). If the complex ion is a cation or neutral, like Fe(CO)5, we call this pentacarbonyliron.
are there any other elements where the latin name is different from the name we know, other than iron?
Wouldn't we only use ferrate if the compound is an anion? I think if the compound is neutral or a cation then we use iron, correct?

Other than iron, I would say these following metals are different from the name that we know.
Copper = Cuprate
Lead = Plumbate
Silver = Argenate
Gold = Aurate
Tin = Stannate
When the coordination compound has a negative charge we would usually add the suffix -ate to the Lewis Acid, but for iron we would change it to ferrate instead.
I believe we really just need to know Ferrate only, although there are those other exceptions.
