Ferrate

Postby Vivian Leung 1C » Wed Dec 02, 2020 9:16 am

Hi everyone,

I just wanted to make sure: Would Iron in Coordination Compounds always be named "ferrate"? For instance, [Fe(CN)6]^4- would be called "hexacyanoferrate (II) ion" rather than "hexacyanoironate (II) ion" right?

Yes, you would use “ferrate” instead of “ironate” in coordination compounds when the overall charge of the compound is negative. However, if there is no charge or the compound is positive, you would just use “iron.” Hope this helps!

Yes, and I believe this is true for the transition metals that have names derived from ancient greek (Fe, Cu, Ag, Au).

If iron is not directly connected to the coordination compound is it considered iron or is it called ferrate if the coordination compound is negative?

It depends on the charge of the overall coordination ion. If it is a positively charged ion, you use ferrate and not ironate. Negatively charge: use iron, not ironate or ferrate.

You would use "-ate" when the overall charge of the complex ion is an anion. Such as ferrate and cobaltate.

Such as Fe is derived from greek to make Ferrate here are some other examples that might be useful to memorize! :)
Cu= Cuprate, Pb=Plumbate, Au= Aurate, Sn=Stannate, Ag=Argentate
