Tb2O3 crystallizes in the cubic Pn-3m space group. Tb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to four equivalent Tb(1) atoms to form a mixture of corner and edge-sharing OTb4 tetrahedra.
Tb2O3 crystallizes in the cubic Pn-3m space group. Tb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. All Tb(1)-O(1) bond lengths are 2.33 Å. O(1) is bonded to four equivalent Tb(1) atoms to form a mixture of corner and edge-sharing OTb4 tetrahedra.
