The material structure described by Pr(O3I)3 crystallizes in the monoclinic P2_1/c space group. Pr(1) is bonded in a 9-coordinate geometry to one O(2), one O(4), one O(6), one O(7), one O(9), two equivalent O(3), and two equivalent O(8) atoms. There are nine inequivalent O sites. In the first O site, O(8) is bonded in a 3-coordinate geometry to two equivalent Pr(1) and one I(1) atom. In the second O site, O(9) is bonded in a distorted bent 120 degrees geometry to one Pr(1) and one I(3) atom. In the third O site, O(1) is bonded in a single-bond geometry to one I(3) atom. In the fourth O site, O(2) is bonded in a 2-coordinate geometry to one Pr(1) and one I(2) atom. In the fifth O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Pr(1) and one I(2) atom. In the sixth O site, O(4) is bonded in a bent 120 degrees geometry to one Pr(1) and one I(3) atom. In the seventh O site, O(5) is bonded in a 2-coordinate geometry to two equivalent I(1) atoms. In the eighth O site, O(6) is bonded in a distorted water-like geometry to one Pr(1) and one I(2) atom. In the ninth O site, O(7) is bonded in a distorted water-like geometry to one Pr(1) and one I(1) atom. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 4-coordinate geometry to one O(7), one O(8), and two equivalent O(5) atoms. In the second I site, I(2) is bonded in a 3-coordinate geometry to one O(2), one O(3), and one O(6) atom.
