A three-dimensional x-ray analylsis of a crystallinie solid of Xe+8 formed by the reaction of XeF6 with sodium hydroxide solution indicates that it is sodium perxenate octahydrate, Na4XeO6 * 8H2O. The perxenate ion, XeO6-4, has approximately a regular octahedral configuration with a mean xenon-oxygen bond length of 1.875 Å.
