### Naming

Can someone walk me through how to name $[Fe(CN)_{6}]^{4-}$ ?

I know that you start with naming the ligand before the TM, so I got to hexacyano, but how did iron become ferrate?

I believe ferrate is the Latin name for iron and we use this name for coordination compounds.

I think you just have to memorize the names. There is a list on page 723/724 in the textbook.

I think it's because the overall compound has a negative charge. Usually when a transition metal is used it has an overall positive charge so it's odd when it's negative. Lavelle said adding -ate to transition metals sounds weird too so use that to remember it's an odd compound with an overall negative charge.

### Re: Naming

Because the coordinate complex has an overall negative charge it is an anion and therefore when naming the overall complex with negative charge -ate is added to the metal. If the symbol of the metal originates from the Latin name, the latin stem is used, therefore for iron Fe, the latin ferrum is used therefore it will be ferrate.
