Xenon fluoride nitrate, also known as fluoroxenonium nitrate, is the chemical compound with formula FXeONO2.[1][2]
Synthesis
[edit]This compound is formed via the reaction:[3]
- [FXeOXeFXeF][AsF6] + 2NO2F → FXeONO2 + NO2AsF6.
Purification of FXeONO2 can then take place by dissolving in SO2ClF, which leaves the nitronium arsenic hexafluoride behind as a solid.[3]
An alternate low yield method to make FXeONO2 is to dissolve xenon difluoride in liquid dinitrogen tetroxide at 0 °C.[3]
- XeF2 + NO+ + NO3− → FXeONO2 + NOF
This method is inefficient as not much nitrate ion exists in the liquid and the xenon fluoride nitrate decomposes.[3]
Another method claimed to make this substance is:[3]
- XeF2 + HNO3 → FXeONO2 + HF
Properties
[edit]FXeONO2 is a white crystalline material.[3] The space group of the crystals is P21/c, which is monoclinic. The unit cell contains four molecules with a total volume of 386.6 Å3. The unit cell dimensions are a = 4.6663 Å, b = 8.799 Å c = 9.415 Å, with non-perpendicular angle β = 90.325°.[3] With a molecular weight of 212.3, the crystal has density 3.648. (These measurements at -173 °C.)[3] The bond lengths in the molecule are 1.992 Å for Xe–F, 2.126 Å for Xe–O, 1.36 Å for O–NO2, 1.199 for N–Ocis and 1.224 Å for N–Otrans.[3] The bond angles are 177.6° for F–Xe–O, 114.7° for Xe-O-N, 114.5° for (Xe)O–N–Ocis, 118.4° for (Xe)O–N–Otrans and 127.1° for Ocis–N–Otrans.[3] The bond lengths and angles on the xenon atom are similar to that in FXeOSO2F and FXeOTeF5, indicating a polar oxygen bond. The Xe–O–N angle is larger than those in halogen nitrates, which indicates a lower bond density for the Xe–O bond. The N–Ocis bond length is longer than the N–Otrans bond length, opposite to other halogen nitrates.[3]
FXeONO2 is not particularly stable and slowly breaks down at -78 °C, yielding XeF2·N2O4. This happens on a timescale of several days.[3] At 0 °C, FXeONO2 has a half life of seven hours, decomposing to XeF2.[3]
