CsPr(WO4)2 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded in a 12-coordinate geometry to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Pr(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 40°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Cs(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Cs(1), two equivalent Pr(1), and one W(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Cs(1), one Pr(1), and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Cs(1), one Pr(1), and one W(1) atom.
