Structure of Xenon hexafluoride -

Distorted octahedral and hybridisation is Sp3d3

- wherein

 

XeF6 cannot be stored in glass because it reacts with the silica present and gives the explosive XeO3

2 XeF_{6}\: \: +\: \: SiO_{2}\rightarrow 2XeOF_{4} + SiF_{4}

2 XeOF_{4}\: \: +\: \: SiO_{2}\rightarrow 2XeO_{2}F_{2} + SiF_{4}

2 XeO_{2}F_{2}\: \: +\: \: SiO_{2}\rightarrow 2XeO_{3} + SiF_{4}
