The crystal structure described by Na is beta structured and crystallizes in the cubic P4_132 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to six equivalent Na(1) and six equivalent Na(2) atoms to form a mixture of distorted face, corner, and edge-sharing NaNa12 cuboctahedra. In the second Na site, Na(2) is bonded to three equivalent Na(2) and nine equivalent Na(1) atoms to form a mixture of distorted face, corner, and edge-sharing NaNa12 cuboctahedra. is represented by the CIF file [CIF]
