The material structure described by Pr2WO6 crystallizes in the monoclinic C2/c space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(5) atoms. In the second Pr site, Pr(2) is bonded in a distorted body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(6) atoms. In the third Pr site, Pr(3) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(6) atoms. W(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Pr(3) and one W(1) atom. In the second O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Pr(3) and one W(1) atom. In the third O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Pr(1) and one W(1) atom. In the fourth O site, O(6) is bonded to two equivalent Pr(2) and two equivalent Pr(3) atoms to form OPr4 tetrahedra that share corners with two equivalent O(6)Pr4 tetrahedra, corners with four equivalent O(1)Pr3W tetrahedra,  an edgeedge with one O(1)Pr3W tetrahedra, and edges with three equivalent O(6)Pr4 tetrahedra. In the fifth O site, O(1) is bonded to one Pr(1), one Pr(2), one Pr(3), and one W(1) atom to form OPr3W tetrahedra that share corners with two equivalent O(1)Pr3W tetrahedra, corners with four equivalent O(6)Pr4 tetrahedra, and  an edgeedge with one O(6)Pr4 tetrahedra. In the sixth O site, O(2) is bonded in a 4-coordinate geometry to one Pr(1), one Pr(2), one Pr(3), and one W(1) atom. is represented by the CIF file [CIF]
