The material described by Yb2O3 is Corundum-like structured and crystallizes in the cubic I2_13 space group. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles range from 56-58°. In the second Yb site, Yb(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles range from 54-58°. In the third Yb site, Yb(3) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form a mixture of distorted edge and corner-sharing YbO6 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Yb(1), one Yb(3), and two equivalent Yb(2) atoms to form a mixture of edge and corner-sharing OYb4 tetrahedra. In the second O site, O(2) is bonded to one Yb(1), one Yb(2), and two equivalent Yb(3) atoms to form a mixture of edge and corner-sharing OYb4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
