Abstract

Abstract: For the first time tetravalent palladium is detected, coordinated exclusively by simple oxoanions. Stabilization was achieved by formation of the [Pd(S2 O7 )3 ] 2− complex in which three chelating disulfate groups surround the metal atom. The salt K2 [Pd(S2 O7 )3 ] could only be obtained if the reaction of K2 [PdCl6 ] and neat SO3 was performed in the presence of XeF2 . Abstract : XeF2 is the key : The first compound containing Pd 4+ in an exclusively oxoanionic environment was obtained under harsh conditions from the reaction of K2 [PdCl6 ], SO3, and XeF2 . In the structure of K2 [Pd(S2 O7 )3 ], stabilization of the Pd 4+ ion is achieved by the coordination of three chelating disulfate anions. The structure of the complex is well reproduced by quantum chemical calculations.
