The crystal structure described by Pr2O16Cl3 crystallizes in the monoclinic C2/c space group. Pr(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(4), one O(5), one O(6), one O(7), one O(8), and two equivalent O(3) atoms. There are eight inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one Pr(1) and one Cl(1) atom. In the second O site, O(5) is bonded in a 2-coordinate geometry to one Pr(1) and one O(3) atom. In the third O site, O(6) is bonded in a bent 150 degrees geometry to one Pr(1) and one Cl(1) atom. In the fourth O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Pr(1) and one Cl(2) atom. In the fifth O site, O(8) is bonded in a distorted single-bond geometry to one Pr(1) and one Cl(2) atom. In the sixth O site, O(1) is bonded in a bent 120 degrees geometry to one Pr(1) and one Cl(1) atom. In the seventh O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Pr(1) and one Cl(1) atom. In the eighth O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Pr(1) and one O(5) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(4), and one O(6) atom. In the second Cl site, Cl(2) is bonded in a tetrahedral geometry to two equivalent O(7) and two equivalent O(8) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
