The structure described by Rb(WO3)6 crystallizes in the orthorhombic Immm space group. Rb(1) is bonded to four equivalent O(3) and eight equivalent O(2) atoms to form RbO12 cuboctahedra that share edges with four equivalent W(2)O6 octahedra and edges with eight equivalent W(1)O6 octahedra. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with two equivalent W(2)O6 octahedra, corners with four equivalent W(1)O6 octahedra, and edges with two equivalent Rb(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-29°. In the second W site, W(2) is bonded to one O(4), one O(5), and four equivalent O(2) atoms to form WO6 octahedra that share corners with two equivalent W(2)O6 octahedra, corners with four equivalent W(1)O6 octahedra, and edges with two equivalent Rb(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-29°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Rb(1), one W(1), and one W(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Rb(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent W(2) atoms. In the fifth O site, O(5) is bonded in a linear geometry to two equivalent W(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
