The standard enthalpy of formation of crystalline (IF3O2)2 has been determined as -984.0 +/- 18.0 kJ mol-1 based on enthalpies of reaction with excess of aqueous acidic iodide solution.The stability of (IF3O2)2 is considered in terms of this va

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.

The structure of the title adduct has been determined by heavy-atom method from 1 451 diffractometer reflections and refined by full-matrix least-squares methods to R 0.074.Crystals are monoclinic, space group P21/c, with unit-cell dimensions a = 5.72(1), b = 9.96(1), c = 12.56(2) Angstroem, β = 101.7(2)deg.The solid adduct exists as dimers with two antimony and two iodine atoms at the corners of a rhombus, linked by asymmetric, angular oxygen bridges, with Sb-O 2.05 and I-O 1.80 Angstroem.Both the SbF4O2 and IF4O2 units have distorted octahedral geometries with cis oxygen bridges, and with a greater distortion in the antimony unit.This can be correlated with a contribution to the structure from the ionic form (SbF4)+(IF4O2)-.The adduct has a very similar structure to pentafluorides typified by RuF5, based on an approximate hexagonal close-packing of the light atoms.
