The compound described by NaSrEuWO6 crystallizes in the tetragonal P-4n2 space group. Na(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NaO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Eu(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), two equivalent Sr(1), two equivalent Eu(1), and one W(1) atom to form distorted ONaSr2Eu2W octahedra that share corners with six equivalent O(1)NaSr2Eu2W octahedra, corners with eight equivalent O(2)NaSrEuW tetrahedra, edges with four equivalent O(1)NaSr2Eu2W octahedra, and edges with eight equivalent O(2)NaSrEuW tetrahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the second O site, O(2) is bonded to one Na(1), one Sr(1), one Eu(1), and one W(1) atom to form distorted ONaSrEuW tetrahedra that share corners with four equivalent O(1)NaSr2Eu2W octahedra, corners with ten equivalent O(2)NaSrEuW tetrahedra, edges with four equivalent O(1)NaSr2Eu2W octahedra, and  an edgeedge with one O(2)NaSrEuW tetrahedra. The corner-sharing octahedral tilt angles range from 65-69°. is represented by the CIF file [CIF]
