Solution Multi-NMR and Raman Spectroscopic Studies of Thermodynamically Unstable XeO4. The First 131Xe NMR Study of a Chemically Bound Xenon Species †

Xenon tetroxide is thermodynamically unstable, decomposing explosively in the gas phase and in the solid state. A modified and more detailed description of the procedure for the preparation of XeO(4) and its solutions is provided. Xenon tetroxide dissolves in SO(2)ClF, BrF(5), and HF solvents, giving solutions that are kinetically stable up to -30 degrees C. The preparation of kinetically stable XeO(4) solutions lays the groundwork for the …
