The material described by Pr9(SbO)5 crystallizes in the tetragonal P4/n space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 4-coordinate geometry to two equivalent Sb(2), one O(1), and three equivalent O(2) atoms. In the second Pr site, Pr(2) is bonded in a distorted single-bond geometry to one Sb(1), four equivalent Sb(2), and one O(1) atom. In the third Pr site, Pr(3) is bonded in a distorted single-bond geometry to one Sb(1), four equivalent Sb(2), and one O(2) atom. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one Pr(2) and four equivalent Pr(3) atoms to form SbPr5 square pyramids that share corners with four equivalent O(2)Pr4 tetrahedra and  a cornercorner with one O(1)Pr5 trigonal bipyramid. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to one Pr(2), two equivalent Pr(1), and four equivalent Pr(3) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Pr(2) and four equivalent Pr(1) atoms to form distorted OPr5 trigonal bipyramids that share  a cornercorner with one Sb(1)Pr5 square pyramid, corners with four equivalent O(2)Pr4 tetrahedra, and edges with four equivalent O(2)Pr4 tetrahedra. In the second O site, O(2) is bonded to one Pr(3) and three equivalent Pr(1) atoms to form OPr4 tetrahedra that share  a cornercorner with one Sb(1)Pr5 square pyramid, corners with four equivalent O(2)Pr4 tetrahedra,  a cornercorner with one O(1)Pr5 trigonal bipyramid,  an edgeedge with one O(2)Pr4 tetrahedra, and  an edgeedge with one O(1)Pr5 trigonal bipyramid. is represented by the Crystallographic Information File (CIF) [CIF]
