Pr(OH)3 crystallizes in the monoclinic P2_1/m space group. Pr(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent Pr(1) and one H(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Pr(1) and one H(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to three equivalent Pr(1) and one H(3) atom.
