Pr(WO3)5 crystallizes in the orthorhombic Pmmm space group. Pr(1) is bonded to four equivalent O(2) and eight equivalent O(4) atoms to form PrO12 cuboctahedra that share edges with four equivalent W(2)O6 octahedra, edges with eight equivalent W(1)O6 octahedra, and faces with two equivalent Pr(1)O12 cuboctahedra. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(2), one O(3), one O(4), one O(6), and two equivalent O(1) atoms to form WO6 octahedra that share  a cornercorner with one W(2)O6 octahedra, corners with five equivalent W(1)O6 octahedra, and edges with two equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 4-50°. In the second W site, W(2) is bonded to two equivalent O(5) and four equivalent O(4) atoms to form WO6 octahedra that share corners with two equivalent W(2)O6 octahedra, corners with four equivalent W(1)O6 octahedra, and edges with four equivalent Pr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-37°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Pr(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Pr(1), one W(1), and one W(2) atom. In the fifth O site, O(5) is bonded in a linear geometry to two equivalent W(2) atoms. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms.
