Materials Data on DyHSe by Materials Project
DyHSe crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Dy3+ is bonded in a distorted trigonal planar geometry to three equivalent H1- and six equivalent Se2- atoms. All Dy–H bond lengths are 2.22 Å. All Dy–Se bond lengths are 2.96 Å. H1- is bonded in a trigonal planar geometry to three equivalent Dy3+ atoms. Se2- is bonded to six equivalent Dy3+ atoms to form a mixture of distorted edge, face, and corner-sharing SeDy6 pentagonal pyramids.
