The material described by Na6OsN4 crystallizes in the tetragonal P4_2/nmc space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a bent 150 degrees geometry to two equivalent N(1) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. Os(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. N(1) is bonded in a 6-coordinate geometry to one Na(1), four equivalent Na(2), and one Os(1) atom. is represented by the CIF file [CIF]
