The material structure described by Pr(O3I)3 crystallizes in the orthorhombic Pmmn space group. Pr(1) is bonded in a 7-coordinate geometry to one O(4), two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Pr(1) and one I(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Pr(1) and two equivalent I(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Pr(1), one I(1), and one I(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Pr(1) and two equivalent I(1) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms. In the second I site, I(2) is bonded in a 4-coordinate geometry to four equivalent O(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
