RbWSbO6 crystallizes in the orthorhombic Imma space group. Rb(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form RbO6 octahedra that share corners with six equivalent W(1)O6 octahedra and corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 67-72°. W(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and corners with six equivalent Rb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-72°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent W(1)O6 octahedra, and corners with six equivalent Rb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-69°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Rb(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Rb(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Rb(1), one W(1), and one Sb(1) atom.
