Naming Coordination Compounds

Postby Monica Habashy 3A » Mon Nov 14, 2016 2:48 pm

If there's an H2O outside the complex, do we refer to it as hydrate or aqua?

For example: K3[Fe(CN6)]3H2O

You would refer to it as aqua because that is the proper ligand name of H2O as mentioned on Page 117 of our coursereader.

Actually, since H2O is outside the coordination sphere (represented by the brackets), it is therefore not directly bound to the metal atom/ion (iron). Since ligands are defined as ions or molecules attached to the central metal atom/ion, H2O is not a ligand so you don't refer to it as aqua. Instead, you refer to it as hydrate.

I hope that helps.
