CsSc(WO4)2 crystallizes in the monoclinic C2/m space group. Cs(1) is bonded in a 10-coordinate geometry to four equivalent O(2) and six equivalent O(1) atoms. Sc(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form ScO6 octahedra that share corners with six equivalent W(1)O4 tetrahedra. W(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form WO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-40°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one W(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Cs(1), one Sc(1), and one W(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Sc(1) and one W(1) atom.
