Sm2O3 crystallizes in the cubic Pn-3m space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to four equivalent Sm(1) atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra.
Sm2O3 crystallizes in the cubic Pn-3m space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. All Sm(1)-O(1) bond lengths are 2.36 Å. O(1) is bonded to four equivalent Sm(1) atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra.
