"Ferrate"

Postby Isabel Day 1D » Wed Dec 04, 2019 7:16 pm

When naming the complex ion (Fe(CN)6)4-, why is iron represented as "ferrate"? Is this just something I have to memorize?

when the transition metal is part of a complex ion that is negatively charged, you would name it using its latin prefix and adding -ate at the end instead of just using its regular name. I would say you should probably know a few of the common latin names besides iron like copper (which is cuprate) and tin (which is stannate)

Are there any more important common ones besides the ones already listed?

I think the one other exception we would need to know is for copper; it has a latin prefix of "cupr"

Does that mean it's incorrect to name a compound using iron(III) instead of ferrate?

When the coordination compund has an overall negative charge, you would use ferrate instead of iron as the metals in a negative coordination complex end in
-ate.

According to the textbook, if an element's name on the periodic table is based on their latin name, then that latin name is used in naming the coordination complex. This is also why copper is represented by "cuprate".

If the complex (inside brackets) is an anion the prefix -ate must be added at the end of the transition metal and iron is part of the exception that uses the beginning of its elemental symbol Fe(rrate)

Ferrate is used when the overall complex has a negative charge and there is Iron in the complex. the same concept works for copper and cupperate.

When the complex ion is an anion, then you have to add -ate to the end of the transition metal name. Some of the metals have exceptions, and have ate added a different way which just has to be memorized.

When the complex is an anion, you use the latin prefix (only if there is one) for the metal, and end it in -ate.

Ferrate follows the rule of naming anions with adding -ate at the end, but use the latin name for Iron just cause it sounds better.

why is it that sometimes in coordination compounds it is just iron and other times it is written as ferrate

Yes, it is latin prefix, and you just have to memorize the exceptions I believe.

In this case it would be ferrate because the coordination compound has a negative charge.
