Na6RuN4 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 2-coordinate 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. Ru(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 Ru(1) atom.
