✦ Synopsis

In view of the recent synthesis and characterization of the novel pentagonal planar (Dsh) XeF,-anion, it was of interest to attempt the synthesis of the corresponding OTeF, substituted anion, Xe(OTeF,),-, as well as the series of mixed F/OTeF, anions, XeF,(OTeF,),_,-(n = 1 -4). So far all efforts to prepare these anions have failed, rather reactions of Xe(OTeF,), with N(CH3),'F-or N(CH,),+OTeF,-in CH,CN have resulted in the formation of the new Xe(IV) oxo-species O=XeF(OTeF,) and O=Xe(OTeF,),. These species, together with the previously known O=XeF,, have been characterized in solution for the first time by '29Xe and 19F NMR spectroscopy.

Analogous reactions with OTeF, derivatives of Xe(V1) and Te(V1) will also be discussed.
