9C 1A

Why is [Fe(CN)6] 4- hexacyanoferrate(Ⅱ) instead of hexacyanoiron(Ⅱ)?

We have to add the -ate to the transition metal since the coordination compound is an anion, and when we do this with iron, we use the latin name of iron (ferrum) and change it to add -ate to it.

iron is a naming exception when it comes to adding the -ate suffix, instead of ironate. We use the roman name of ferrum, then add the suffix.

Yes it does matter. Iron is one of the naming exceptions where it has a different name instead of just adding -ate to the end to become ironate.
