The novel xenon(II) derivatives FXeOIOF4 and Xe(OIOF4)2 have been shown by their solution 19F and 129Xe NMR spectra to result from the reaction between IO2F3 and XeF2 in SO2ClF, CFCl3, and BrF5 solvents. The covalently bonded -QIF4O groups are shown to be equilibrium mixtures of their cis and trans isomers and are oxygen-bonded to xenon. The solid derivative cis,cis-Xe(OIOF4)2 has been isolated from the acid displacement reaction between Xe(OTeF5)2 and the strong protonic acid cis/trans-HOIOF4. In addition, a mixture of cis- and trans-FXeOIOF4 was prepared by the reaction of stoichiometric amounts of IO2F3 and XeF2 in HF solvent. Both cis- and trans-FXeOIOF4 and cis,cis-Xe(OIOF4)2 were characterized by 19F and 129Xe NMR spectroscopy and low-temperature Raman spectroscopy. A comparison of 129Xe NMR chemical shifts among Xe(II) compounds, including the mixed derivatives F4OIOXeOSO2F and F4OIOXeOTeF5, indicates the effective group electronegativity order is -F > -OSO2F > trans-OIF4O > cis-OIF4O > -OTeF5.
