The crystal structure described by NaEuPrWO6 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 0-34°. Eu(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Pr(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 0-34°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), two equivalent Eu(1), two equivalent Pr(1), and one W(1) atom to form distorted ONaPr2Eu2W octahedra that share corners with six equivalent O(1)NaPr2Eu2W octahedra, corners with eight equivalent O(2)NaPrEuW tetrahedra, edges with four equivalent O(1)NaPr2Eu2W octahedra, and edges with eight equivalent O(2)NaPrEuW tetrahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second O site, O(2) is bonded to one Na(1), one Eu(1), one Pr(1), and one W(1) atom to form distorted ONaPrEuW tetrahedra that share corners with four equivalent O(1)NaPr2Eu2W octahedra, corners with ten equivalent O(2)NaPrEuW tetrahedra, edges with four equivalent O(1)NaPr2Eu2W octahedra, and  an edgeedge with one O(2)NaPrEuW tetrahedra. The corner-sharing octahedral tilt angles range from 65-68°. is represented by the Crystallographic Information File (CIF) [CIF]
