The material structure described by Na2WO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Na(1) is bonded to six equivalent O(1) atoms to form NaO6 octahedra that share corners with six equivalent W(1)O4 tetrahedra and edges with six equivalent Na(1)O6 octahedra. W(1) is bonded to four equivalent O(1) atoms to form WO4 tetrahedra that share corners with twelve equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles are 51°. O(1) is bonded in a rectangular see-saw-like geometry to three equivalent Na(1) and one W(1) atom. is represented by the CIF file [CIF]
