Thermochemistry of Fluorine Compounds. Part 5. Di-μ-oxo-bis

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

Fluoride Crystal Structures. Part 34. Antimony Pentafluoride-Iodine Trifluoride Dioxide.

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.
