The material described by Sm9(SbO)5 crystallizes in the tetragonal P4/n space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 4-coordinate geometry to two equivalent Sb(1), one O(2), and three equivalent O(1) atoms. In the second Sm site, Sm(2) is bonded in a distorted single-bond geometry to one Sb(2), four equivalent Sb(1), and one O(1) atom. In the third Sm site, Sm(3) is bonded in a distorted single-bond geometry to one Sb(2), four equivalent Sb(1), and one O(2) atom. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 7-coordinate geometry to one Sm(3), two equivalent Sm(1), and four equivalent Sm(2) atoms. In the second Sb site, Sb(2) is bonded to one Sm(3) and four equivalent Sm(2) atoms to form SbSm5 square pyramids that share corners with four equivalent O(1)Sm4 tetrahedra and  a cornercorner with one O(2)Sm5 trigonal bipyramid. There are two inequivalent O sites. In the first O site, O(2) is bonded to one Sm(3) and four equivalent Sm(1) atoms to form distorted OSm5 trigonal bipyramids that share  a cornercorner with one Sb(2)Sm5 square pyramid, corners with four equivalent O(1)Sm4 tetrahedra, and edges with four equivalent O(1)Sm4 tetrahedra. In the second O site, O(1) is bonded to one Sm(2) and three equivalent Sm(1) atoms to form OSm4 tetrahedra that share  a cornercorner with one Sb(2)Sm5 square pyramid, corners with four equivalent O(1)Sm4 tetrahedra,  a cornercorner with one O(2)Sm5 trigonal bipyramid,  an edgeedge with one O(1)Sm4 tetrahedra, and  an edgeedge with one O(2)Sm5 trigonal bipyramid. is represented by the CIF file [CIF]
