High Quality Content by WIKIPEDIA articles! Xenon difluoride is a powerful fluorinating agent with the chemical formula XeF2, and one of the most stable xenon compounds. Like most covalent inorganic fluorides it is moisture sensitive. It decomposes on contact with light or water vapour. Xenon difluoride is a dense, white crystalline solid. It has a nauseating odour but low vapor pressure. It has a strong characteristic infrared doublet at 550 cm–1 and 556 cm–1.Xenon difluoride is a linear molecule with an Xe–F bond length of 197.73±0.15 pm in the vapor phase, and 200 pm in the solid phase. The packing arrangement in solid XeF2 shows that the fluorine atoms of neighbouring molecules avoid the equitorial region of each XeF2 molecule.
