Naming Coordination Complexes: Ion

Postby Clarissa Cabil 1I » Thu Dec 06, 2018 8:45 am

Just to verify, when naming coordination complexes that have a charge, do we always write "ion" at the end of the name?

When I went to a review session, we always wrote ion if the coordination complexes had a charge outside of the brackets, but in one of Dr. Lavelle's examples during lecture for [Ni(CN4)]2- he named it tetracyanonickelate (II), but didn't write "ion" at the end.

Can someone clarify this for me?

A good rule of thumb is to add "ion" at the end if there is an overall charge on the complex. The "ate" implies that it's an ion, but adding on ion makes it more clear.
