The structure described by Pr(WO4)2 crystallizes in the triclinic P-1 space group. Pr(1) is bonded in a 8-coordinate geometry to one O(1), one O(3), one O(4), one O(5), one O(6), one O(8), and two equivalent O(2) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and two equivalent O(7) atoms. In the second W site, W(2) is bonded in a distorted octahedral geometry to one O(1), one O(3), one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Pr(1), one W(1), and one W(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to 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 Pr(1), one W(1), and one W(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Pr(1) and one W(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Pr(1) and one W(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Pr(1) and one W(2) atom. In the seventh O site, O(7) is bonded in a trigonal non-coplanar geometry to one W(2) and two equivalent W(1) atoms. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to one Pr(1) and one W(2) atom. is represented by the CIF file [CIF]
