Materials Data on Ho2ZnPd by Materials Project

Ho2PdZn is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ho is bonded in a body-centered cubic geometry to four equivalent Pd and four equivalent Zn atoms. All Ho–Pd bond lengths are 3.04 Å. All Ho–Zn bond lengths are 3.04 Å. Pd is bonded in a body-centered cubic geometry to eight equivalent Ho atoms. Zn is bonded in a body-centered cubic geometry to eight equivalent Ho atoms.

Materials Data on HoZnPd by Materials Project

HoPdZn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ho is bonded in a 11-coordinate geometry to five Pd and six equivalent Zn atoms. There are four shorter (2.93 Å) and one longer (2.95 Å) Ho–Pd bond lengths. There are two shorter (3.16 Å) and four longer (3.22 Å) Ho–Zn bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 9-coordinate geometry to three equivalent Ho and six equivalent Zn atoms. All Pd–Zn bond lengths are 2.65 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent Zn atoms. All Pd–Zn bond lengths are 2.78 Å. Zn is bonded in a 4-coordinate geometry to six equivalent Ho and four Pd atoms.
