Only minimally distorted by interionic forces in the crystal, the ion XeOF 5 −(picture on the right, bond lengths in pm) can be crystallized as NO + XeOF 5 − . The xenon atom is situated only slightly above the plane through the fluorine atoms, and the doubly bonded oxygen atom occupies the apical position of the pentagonal pyramid. NO + XeOF 5 −is formed directly by treatment of NOF with an equimolar amount of XeOF 4 and crystallizes spontaneously from the liquid phase.
