Sodium perxenate octahydrate, Na4XeO6· 8H2O, is orthorhombic with cell constants a = 11.86, b = 10.36, c = 10.43 Å., space group Pbcn, Z = 4. A three-dimensional X-ray diffraction investigation has resulted in a complete structure determination. The perxenate ion is approximately a regular octahedron with a mean Xe-O distance of 1.864 ± 0.012 Å. The greatest deviation of an O-Xe-O angle from the ideal 90° is 2.6 ± 0.8°. The two crystallographically independent sodium atoms are surrounded by very distorted octahedra composed of water molecules and perxenate oxygen atoms. A complex array of hydrogen bonds completes the structure.
