In 1962, N. Bertlett noticed that platínum hexafluoride (PtF6) is a powerful oxidising agent which combines with molecular oxygen to form ionic compound dioxygen hexafluoroplatinate (v) O+2 [PtF6]–
O2(g) + PtF6(aq) → O+2[PtF6]
This indicates that PtFo can oxidised O2 to O+2. Oxygen and Xenon, have some similarities:
1. The first ionisation enthalpy of Xenone gas (1170 kJ mol-1) is fairly close to that of Oxygen(1166 kJ mol-1)
2. The molecular diameter of Oxygen and atomic radius of Xenon are similar.
