The corner-sharing octahedral tilt angles range from 45-51°. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to one Na(1), two equivalent Na(2), two equivalent Na(3), and one W(1) atom to form ClNa5W octahedra that share corners with four equivalent Cl(1)Na5W octahedra, corners with twelve equivalent O(1)Na3W2 square pyramids, edges with four equivalent Cl(2)Na4W square pyramids, and faces with four equivalent O(1)Na3W2 square pyramids. The corner-sharing octahedral tilt angles range from 22-23°.

In the fourth Cl site, Cl(4) is bonded in a square co-planar geometry to one Na(2), two equivalent Na(1), and one W(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
