The material structure described by Na4WO5 crystallizes in the triclinic P-1 space group. There are five inequivalent Na sites. In the first Na site, Na(1) is bonded in a 2-coordinate geometry to one Na(5), two equivalent W(1), one O(3), and one O(4) atom. In the second Na site, Na(2) is bonded in a 3-coordinate geometry to one Na(5), one W(1), one O(1), and one O(2) atom. In the third Na site, Na(3) is bonded in a 1-coordinate geometry to one Na(4), one W(1), and one O(2) atom. In the fourth Na site, Na(4) is bonded in a 4-coordinate geometry to two equivalent Na(3) and two equivalent W(1) atoms. In the fifth Na site, Na(5) is bonded in a 12-coordinate geometry to two equivalent Na(1), two equivalent Na(2), two equivalent W(1), two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms. W(1) is bonded in a 10-coordinate geometry to one Na(2), one Na(3), one Na(4), one Na(5), two equivalent Na(1), one O(1), one O(3), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one Na(2), one Na(5), one W(1), and one O(4) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Na(2) and one Na(3) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Na(1) and one W(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Na(1), one Na(5), one W(1), and one O(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Na(5) and one W(1) atom. is represented by the CIF card [CIF]
