Materials Data on Hf6Be15Pd8 by Materials Project

Abstract

Be15Hf6Pd8 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are three inequivalent Be sites. In the first Be site, Be is bonded to four equivalent Be, four equivalent Hf, and four equivalent Pd atoms to form a mixture of distorted corner and face-sharing BeHf4Be4Pd4 cuboctahedra. All Be–Be bond lengths are 2.33 Å. All Be–Hf bond lengths are 2.92 Å. All Be–Pd bond lengths are 2.47 Å. In the second Be site, Be is bonded in a body-centered cubic geometry to eight equivalent Pd atoms. All Be–Pd bond lengths are 2.47 Å. In the third Be site, Be is bonded in a 3-coordinate geometry to six Be, three equivalent Hf, and three equivalent Pd atoms. All Be–Be bond lengths are 2.47 Å. All Be–Hf bond lengths are 2.81 Å. All Be–Pd bond lengths are 2.43 Å. Hf is bonded in a 8-coordinate geometry to eight Be and four equivalent Pd atoms. All Hf–Pd bond lengths are 2.86 Å. Pd is bonded in a 10-coordinate geometry to seven Be and three equivalent Hf atoms.
