Iron

When naming a coordination compound with iron as the transition metal, would you use Iron or Ferris if it was a cation?

As a cation it would be iron, as an anion it would be ferrate.

I know iron is a common transition metal which changes to ferrate when it is an anion. I was wondering if copper did the same thing where copper as a cation is “copper” and as an anion it is “cuprate”?

Yes, Cuprate refers to the copper anion

this may be a stupid question, but for example 17.29 a) [Fe(CN)6]4- why is Fe the anion?? As in why is it ferrate?

Hello,

First of all it is not a stupid question. Secondly, professor Lavelle mentioned in lecture than when a complex has a negative charge (which is pretty uncommon) it has a anion. For this case, the complex has a 4- charge. Adding on the CN has a -1 charge. Since there are 6 of them, the charge is -6. We know that the complex has a 4- charge so we can conclude that Fe has a +2 charge. This is why it sis ferrate (II).

Hope that helps :)
