Materials Data on Ho(AsO)2 by Materials Project
Ho(AsO)2 crystallizes in the tetragonal I4_1/amd space group. The structure is zero-dimensional and consists of eight Ho(AsO)2 clusters. Ho3+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ho–O bond lengths are 2.11 Å. As+0.50+ is bonded in a single-bond geometry to one O2- atom. The As–O bond length is 1.78 Å. O2- is bonded in a distorted linear geometry to one Ho3+ and one As+0.50+ atom.
