The material described by RbSc(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. Sc(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted ScO6 pentagonal pyramids that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 23-63°. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with four equivalent Sc(1)O6 pentagonal pyramids, and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Rb(1) and two equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing ORb2W2 trigonal pyramids. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Sc(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 Sc(1), and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one Rb(1), one Sc(1), and one W(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
