The compound described by Sm3SbO3 crystallizes in the monoclinic C2/m space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a distorted see-saw-like 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 see-saw-like geometry to two equivalent Sb(1), one O(1), one O(3), and two equivalent O(2) atoms. In the third Sm site, Sm(3) is bonded in a 4-coordinate geometry to four equivalent Sb(1), one O(2), and three equivalent O(3) atoms. Sb(1) is bonded in a body-centered cubic geometry to two equivalent Sm(1), two equivalent Sm(2), and four equivalent Sm(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Sm(2) and three equivalent Sm(1) atoms to form a mixture of corner and edge-sharing OSm4 trigonal pyramids. In the second O site, O(2) is bonded to one Sm(1), one Sm(3), and two equivalent Sm(2) atoms to form a mixture of distorted corner and edge-sharing OSm4 trigonal pyramids. In the third O site, O(3) is bonded to one Sm(2) and three equivalent Sm(3) atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
