Complexes question!

Okay, simple and probably stupid question: why is permanganate not a coordination compound?after all it's a metal and oxygens which can act as ligands right?

thank you!!

What makes you think it isn't?

It's not simple nor stupid at all. Coordination compounds are defined rather through their fomation than their actual bonding properties. Usually coordinate covalent bonding is understood as a transfer of lone electron pair of a donor ligand (can be ion or neutral molecule) to a bond with central (acceptor) atom. Permanganate is not considered a coordination compound, since no chemist would think of it as a product of Mn7+ cation and 4 O2- anions.

ooooh okay, I see. So what would it be then?

Just ordinary inorganic anion, no need for a special name.
