Materials Data on LuHSe by Materials Project
LuHSe crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Lu3+ is bonded in a distorted trigonal planar geometry to three equivalent H1- and six equivalent Se2- atoms. All Lu–H bond lengths are 2.17 Å. All Lu–Se bond lengths are 2.90 Å. H1- is bonded in a trigonal planar geometry to three equivalent Lu3+ atoms. Se2- is bonded to six equivalent Lu3+ atoms to form a mixture of distorted edge, corner, and face-sharing SeLu6 pentagonal pyramids.
