Materials Data on HoSbPt by Materials Project

HoPtSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ho3+ is bonded to four equivalent Pt2- and six equivalent Sb1- atoms to form a mixture of distorted face and corner-sharing HoSb6Pt4 tetrahedra. All Ho–Pt bond lengths are 2.86 Å. All Ho–Sb bond lengths are 3.30 Å. Pt2- is bonded in a body-centered cubic geometry to four equivalent Ho3+ and four equivalent Sb1- atoms. All Pt–Sb bond lengths are 2.86 Å. Sb1- is bonded in a 10-coordinate geometry to six equivalent Ho3+ and four equivalent Pt2- atoms.

Materials Data on Ho5SbPt2 by Materials Project

Ho5Pt2Sb crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded to four equivalent Pt and two equivalent Sb atoms to form distorted corner-sharing HoSb2Pt4 octahedra. The corner-sharing octahedra tilt angles range from 0–49°. All Ho–Pt bond lengths are 2.99 Å. Both Ho–Sb bond lengths are 3.42 Å. In the second Ho site, Ho is bonded in a 5-coordinate geometry to three equivalent Pt and two equivalent Sb atoms. There are one shorter (2.93 Å) and two longer (2.97 Å) Ho–Pt bond lengths. Both Ho–Sb bond lengths are 3.29 Å. Pt is bonded in a 8-coordinate geometry to eight Ho atoms. Sb is bonded in a 10-coordinate geometry to ten Ho atoms.
