Materials Data on Ho2O3 by Materials Project
Ho2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing HoO6 octahedra. The corner-sharing octahedra tilt angles range from 54–56°. There are a spread of Ho–O bond distances ranging from 2.25–2.34 Å. In the second Ho3+ site, Ho3+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Ho–O bond lengths are 2.29 Å. O2- is bonded to four Ho3+ atoms to form a mixture of distorted edge and corner-sharing OHo4 trigonal pyramids.
