Materials Data on HoHSe by Materials Project
HoHSe crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ho3+ is bonded in a distorted trigonal planar geometry to three equivalent H1- and six equivalent Se2- atoms. All Ho–H bond lengths are 2.21 Å. All Ho–Se bond lengths are 2.94 Å. H1- is bonded in a trigonal planar geometry to three equivalent Ho3+ atoms. Se2- is bonded to six equivalent Ho3+ atoms to form a mixture of distorted face, edge, and corner-sharing SeHo6 pentagonal pyramids.
