The material structure described by Rb(WO4)8 crystallizes in the monoclinic C2/m space group. Rb(1) is bonded in a distorted square co-planar geometry to four equivalent O(6) atoms. 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(4), one O(8), and one O(9) atom to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-16°. In the second W site, W(2) is bonded to one O(10), one O(11), one O(3), one O(4), one O(5), and one O(6) atom to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 8-19°. There are eleven inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one W(2) atom. In the second O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Rb(1) and one W(2) atom. In the third O site, O(7) is bonded in a distorted water-like geometry to two equivalent O(1) atoms. In the fourth O site, O(8) is bonded in a linear geometry to two equivalent W(1) atoms. In the fifth O site, O(9) is bonded in a linear geometry to two equivalent W(1) atoms. In the sixth O site, O(10) is bonded in a bent 150 degrees geometry to two equivalent W(2) atoms. In the seventh O site, O(11) is bonded in a linear geometry to two equivalent W(2) atoms. In the eighth O site, O(1) is bonded in a single-bond geometry to one W(1) and one O(7) atom. In the ninth O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the tenth O site, O(3) is bonded in a linear geometry to one W(1) and one W(2) atom. In the eleventh O site, O(4) is bonded in a linear geometry to one W(1) and one W(2) atom. is represented by the CIF card [CIF]
