The material structure described by NaWO4 crystallizes in the triclinic P-1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), one O(7), and one O(8) atom. In the second Na site, Na(2) is bonded to one O(1), one O(8), two equivalent O(4), and two equivalent O(7) atoms to form NaO6 octahedra that share corners with three equivalent W(1)O6 octahedra and edges with two equivalent Na(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-58°. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form distorted WO6 octahedra that share corners with three equivalent Na(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-58°. In the second W site, W(2) is bonded in a 6-coordinate geometry to one O(3), one O(4), one O(5), one O(6), and two equivalent O(2) atoms. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Na(2), and one W(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one W(1) and two equivalent W(2) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Na(1), one W(1), and one W(2) atom. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Na(1), two equivalent Na(2), and one W(2) atom. In the fifth O site, O(5) is bonded in a distorted linear geometry to one W(1) and one W(2) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one W(1) and one W(2) atom. In the seventh O site, O(7) is bonded in a distorted rectangular see-saw-like geometry to one Na(1), two equivalent Na(2), and one W(1) atom. In the eighth O site, O(8) is bonded in an L-shaped geometry to one Na(1) and one Na(2) atom. is represented by the CIF file [CIF]
