The material structure described by Lu2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 54-56°. In the second Lu site, Lu(2) is bonded to six equivalent O(1) atoms to form a mixture of edge and corner-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles are 56°. O(1) is bonded to one Lu(2) and three equivalent Lu(1) atoms to form a mixture of edge and corner-sharing OLu4 trigonal pyramids. is represented by the CIF file [CIF]
