Which is not formed in the reaction of "Xe" with F_(2)

The first real compound of noble gases was made in 1962 by Bartlett, soon after this there was a rapid extension of the chemistry of the noble gases and in particular of xenon. Xenon reacts directly with fluorine when heated at 400^(@)C in a sealed nickel tube. The products depend on the ratio of Xe and F_(2).A 1:20 mixture of Xe and F_(2) on heating gives XeF_(6) , which is a white solid. if undergoes slow hydrolysis in small quantity of water forming a xenon oxyfluoride A with Xe,O and F weight ratio 2.62:0.32:1.52. It undergoes complete hydrolysis in excess of water forming an oxide B in the same oxidation state. when the oxide B reacts with A it forms another compound C with formula XeO_(2)F_(2). XeF_(6) can act as a fluoride donor and forms a complex D with AsF_(5) . The complex in the crystalline form is found to contain monovalent ions in which Xe is present in the cationic part. (Atomic weight of Xe = 131 ) The shape of the molecule B is:
