摘要：

The crystal structure of dehydrated NaX, composition Na88Al88Si104O384, a(0) = 25.099(5) Angstrom, has been determined using single-crystal X-ray diffraction methods and refined in space group Fd3. Diffraction symmetry and refined T-O distances indicate substantial ordering of Si and Al in the T sites. All Na+ cations were located. Site occupancies on a unit cell basis are: site I = 2.9, site I' = 29.1, site II = 31.0, and site III = 29.8. Na+ ions in sites I' and III are split between two and three closely related positions, respectively.
