Na6N4S 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 distorted 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. N(1) is bonded in a 6-coordinate geometry to one Na(1), four equivalent Na(2), and one S(1) atom. S(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms.
Na6N4S 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 distorted bent 150 degrees geometry to two equivalent N(1) atoms. Both Na(1)-N(1) bond lengths are 2.36 Å. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. There are two shorter (2.42 Å) and two longer (2.47 Å) Na(2)-N(1) bond lengths. N(1) is bonded in a 6-coordinate geometry to one Na(1), four equivalent Na(2), and one S(1) atom. The N(1)-S(1) bond length is 1.65 Å. S(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms.
