The discussion revolves around the classification of permanganate as a coordination compound, exploring the definitions and bonding characteristics that differentiate it from such compounds. The scope includes conceptual clarification and technical explanation regarding coordination chemistry.
Participants express differing views on the classification of permanganate, with no consensus reached on whether it should be considered a coordination compound or not.
The discussion highlights the importance of definitions in chemistry and the potential ambiguity in classifying compounds based on their bonding characteristics and formation processes.

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?
