The structure described by Na4N3Br crystallizes in the orthorhombic Pnnm space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 2-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent Br(1) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one N(1), two equivalent N(2), and three equivalent Br(1) atoms. In the third Na site, Na(3) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent Br(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to one Na(2), two equivalent Na(1), and four equivalent Na(3) atoms. In the second N site, N(2) is bonded in a rectangular see-saw-like geometry to one Na(1), one Na(2), and two equivalent Na(3) atoms. Br(1) is bonded in a 9-coordinate geometry to two equivalent Na(1), three equivalent Na(2), and four equivalent Na(3) atoms. is represented by the CIF card [CIF]
