The material structure described by RbP4(WO4)8 crystallizes in the monoclinic C2/m space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(8) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(10), one O(11), one O(5), one O(7), and one O(9) atom to form WO6 octahedra that share corners with two equivalent W(2)O6 octahedra, corners with three equivalent W(1)O6 octahedra, and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 0-12°. In the second W site, W(2) is bonded to one O(3), one O(4), one O(6), one O(7), one O(8), and one O(9) atom to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with two equivalent W(2)O6 octahedra, and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 0-15°. P(1) is bonded to one O(1), one O(2), one O(3), and one O(8) atom to form PO4 tetrahedra that share  a cornercorner with one W(1)O6 octahedra, corners with two equivalent W(2)O6 octahedra, and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 31-37°. There are eleven inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one W(2) and one P(1) atom.
