Can zinc really exist in its oxidation state +III?
Tobias Schlöder, Martin Kaupp, Sebastian Riedel – 2012
Very recently, a thermochemically stable ZnIII complex has been predicted by Samanta and Jena ( J. Am. Chem. Soc. 2012, 134, 8400−8403). In contrast to their conclusions we show here by quantum chemical calculations that (a) Zn(AuF₆)₃ is not a thermochemically feasible compound, and (b) even if it could be made, it would not represent a ZnIII oxidation state by any valid definition.
