The crystal structure described by RbSm(WO4)2 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(2) atoms. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Rb(1), two equivalent Sm(1), and one W(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Rb(1), one Sm(1), and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Rb(1), one Sm(1), and one W(1) atom. is represented by the CIF card [CIF]
