Na2PrWO6 crystallizes in the cubic Pn-3 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted q6 geometry to twelve equivalent O(1) atoms. In the second Na site, Na(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 27°. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 27°. O(1) is bonded in a 3-coordinate geometry to one Na(1), one Na(2), one Pr(1), and one W(1) atom.
