Die Strukturen der Xe-Fluoride können generell nach dem VSEPR-Konzept erklärt werden. When the fluorides of xenon have formed the electrons in the valence shell of xenon get unpaired and are promoted to vacant 5d orbitals. Möglicherweise unterliegen die Inhalte jeweils zusätzlichen Bedingungen. The preference of XeF6 for either a trigonally distorted or a regular octahedral structure is determined by a delicate balance of several competing factors. While in [Ni(CN) 4] 2-the structure of the compound is square and hence has a centre of symmetry and hence it is Laporte forbidden and hence d-d transition is not allowed here with dsp 2 hybridization. Sie wurde 1962 als dritte Verbindung eines Edelgases nach Xenonhexafluoroplatinat (XePtF6)[8] und Xenontetrafluorid (XeF4)[9] erstmals durch Rudolf Hoppe synthetisiert.
