The crystal structure described by Pr3ReO8 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), one O(7), one O(8), two equivalent O(5), and two equivalent O(6) atoms. In the second Pr site, Pr(2) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), and two equivalent O(7) atoms. In the third Pr site, Pr(3) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), and two equivalent O(8) atoms. Re(1) is bonded in an octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(5) is bonded to one Pr(2), one Pr(3), and two equivalent Pr(1) atoms to form distorted OPr4 tetrahedra that share corners with two equivalent O(5)Pr4 tetrahedra, corners with four equivalent O(2)Pr3Re trigonal pyramids, and edges with three equivalent O(6)Pr4 tetrahedra. In the second O site, O(6) is bonded to one Pr(2), one Pr(3), and two equivalent Pr(1) atoms to form OPr4 tetrahedra that share corners with two equivalent O(6)Pr4 tetrahedra, corners with four equivalent O(2)Pr3Re trigonal pyramids, and edges with three equivalent O(5)Pr4 tetrahedra. In the third O site, O(7) is bonded in a 4-coordinate geometry to one Pr(1), two equivalent Pr(2), and one Re(1) atom. In the fourth O site, O(8) is bonded in a 4-coordinate geometry to one Pr(1), two equivalent Pr(3), and one Re(1) atom. In the fifth O site, O(1) is bonded in a distorted single-bond geometry to one Pr(2), one Pr(3), and one Re(1) atom. In the sixth O site, O(2) is bonded to one Pr(1), one Pr(2), one Pr(3), and one Re(1) atom to form distorted corner-sharing OPr3Re trigonal pyramids. In the seventh O site, O(3) is bonded in a 4-coordinate geometry to one Pr(1), one Pr(2), one Pr(3), and one Re(1) atom. In the eighth O site, O(4) is bonded in a 3-coordinate geometry to one Pr(2), one Pr(3), and one Re(1) atom. is represented by the CIF file [CIF]
