The crystal structure described by Na3W2N5 is Chalcostibite-like structured and crystallizes in the tetragonal I4_1 space group. There are four inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one N(1), one N(3), one N(4), and two equivalent N(2) atoms. In the second Na site, Na(2) is bonded in a distorted trigonal non-coplanar geometry to one N(1), one N(4), and one N(5) atom. In the third Na site, Na(3) is bonded in a 6-coordinate geometry to two equivalent N(2), two equivalent N(3), and two equivalent N(5) atoms. In the fourth Na site, Na(4) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one N(1), one N(5), and two equivalent N(3) atoms to form corner-sharing WN4 tetrahedra. In the second W site, W(2) is bonded to one N(2), one N(5), and two equivalent N(4) atoms to form corner-sharing WN4 tetrahedra. There are five inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to one Na(1), one Na(2), one Na(4), and one W(1) atom. In the second N site, N(2) is bonded to one Na(3), one Na(4), two equivalent Na(1), and one W(2) atom to form distorted NNa4W trigonal bipyramids that share corners with two equivalent N(2)Na4W trigonal bipyramids, corners with three equivalent N(5)Na2W2 trigonal pyramids, and  an edgeedge with one N(2)Na4W trigonal bipyramid. In the third N site, N(3) is bonded in a 4-coordinate geometry to one Na(1), one Na(3), and two equivalent W(1) atoms. In the fourth N site, N(4) is bonded in a 4-coordinate geometry to one Na(1), one Na(2), and two equivalent W(2) atoms. In the fifth N site, N(5) is bonded to one Na(2), one Na(3), one W(1), and one W(2) atom to form distorted NNa2W2 trigonal pyramids that share corners with three equivalent N(2)Na4W trigonal bipyramids and  a cornercorner with one N(5)Na2W2 trigonal pyramid. is represented by the CIF file [CIF]
