The compound described by Ho2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles range from 54-56°. In the second Ho site, Ho(2) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles are 56°. O(1) is bonded to one Ho(2) and three equivalent Ho(1) atoms to form a mixture of corner and edge-sharing OHo4 trigonal pyramids. is represented by the CIF file [CIF]
