Permanganate (MnO4-) is not classified as a coordination compound due to its formation characteristics. Coordination compounds are defined by the bonding process involving a central atom and donor ligands, typically involving coordinate covalent bonding. In the case of permanganate, it is recognized as an ordinary inorganic anion rather than a product of a Mn7+ cation and four O2- anions. This distinction is crucial for understanding the nature of chemical compounds in inorganic chemistry.

thank you!

asym said: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.
Just ordinary inorganic anion, no need for a special name.Chemist20 said:ooooh okay, I see. So what would it be then?
