N. Bartlett successfuly prepared O2[PtF6]. Since ionisation energy of O2 molecule (1175 kJ mol-1) is quite closer to the ionisation energy of Xe. Hence he carried out the reaction between Xe and PtF6 which was successful and gave first noble gas compound.
- Xe + PtF6 \(\overset{278K}{\longrightarrow}\) Xe+[PtF6]–
