Solvolysis reactions of the parent compounds, Xe(OTeF5)4 and O=Xe(OTeF5)4, in the strong F/OTeF5 acceptor solvent SbF5, led to OTeF5/F ligand redistribution and formation of two series of novel mixed-xenon cations, FxXe(OTeF5)3-x+, O=XeFx(OTeF5)3-x+ (x = 0-2), and O2XeOTeF5+. The previously known XeF3+, XeOF3+, and XeO2F+ cations were observed in addition to the mixed cations. Decomposition of O=XeF2OTeF5+ and O=XeF-(OTeF5)2+ in SbF5 solution led respectively to formation of the previously known XeO2F+ cation and its novel OTeF5 analog O2XeOTeF5+. The O=Xe(OTeF5)3+ cation was not observed in the O=Xe(OTeF5)4/SbF5 systems but was prepared by allowing O=Xe(OTeF5)4 and "Sb(OTeF5)5" to react in SO2ClF. All three series of cations have been characterized in solution by 129Xe and 19F NMR spectroscopy.
