Yb2O3 is Spinel-derived structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles are 57°. In the second Yb site, Yb(2) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. O(1) is bonded to one Yb(1) and three equivalent Yb(2) atoms to form a mixture of corner and edge-sharing OYb4 tetrahedra.

In the first Yb site, Yb(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Yb(1)-O(1) bond lengths are 2.30 Å. In the second Yb site, Yb(2) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. There are a spread of Yb(2)-O(1) bond distances ranging from 2.28-2.32 Å. O(1) is bonded to one Yb(1) and three equivalent Yb(2) atoms to form a mixture of corner and edge-sharing OYb4 tetrahedra.
