The first compound of the noble gases was made in 1962. Barlett and Lohman had previously used the highly oxidizing compound platium hexaflouride to oxidize dioxygen.
`O_(2)+PtF_(6) to O_(2)^(+)[PtF_(6)]^(-)`
The first ionization energy for `O_(2) to O_(2)` is `1165kJ*mol^(-1)`, which is almost as the value of `1170kJ*mol^(-1)` for `Xe to Xe^(+)`. It was predicated that xenon should react with `PtF_(6)`. Experimental showed that when deep of red `PtF_(6)` vapour was mixed with an equal volume of Xe the gases combined immediately at room temperature to produce a solid.
`Xe+PtF_(6) to Xe[PtF_(6)]`
