Xenon Trioxide Adducts of O‐Donor Ligands; [(CH3)2CO]3XeO3, [(CH3)2SO]3(XeO3)2, (C5H5NO)3(XeO3)2, and [(C6H5)3PO]2XeO3

Xenon trioxide (XeO₃ ) forms adducts with triphenylphosphine oxide, dimethylsulfoxide, pyridine-N-oxide, and acetone by coordination of the ligand oxygen atoms to the Xe^VI atom of XeO₃ . The crystalline adducts were characterized by low-temperature, single-crystal X-ray diffraction, and Raman spectroscopy. Unlike solid XeO₃ , which detonates when mechanically or thermally shocked, solid (C₅ H₅ NO)₃ (XeO₃ )₂ , [(C₆ H₅ )₃ PO]₂ XeO₃ , and [(CH₃ )₂ …
