Materials Data on HfBe2Bi by Materials Project

Abstract

Be2HfBi is alpha bismuth trifluoride-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Be sites. In the first Be site, Be is bonded to four equivalent Hf atoms to form corner-sharing BeHf4 tetrahedra. All Be–Hf bond lengths are 2.90 Å. In the second Be site, Be is bonded to four equivalent Bi atoms to form corner-sharing BeBi4 tetrahedra. All Be–Bi bond lengths are 2.90 Å. Hf is bonded in a body-centered cubic geometry to four equivalent Be and four equivalent Bi atoms. All Hf–Bi bond lengths are 2.90 Å. Bi is bonded in a body-centered cubic geometry to four equivalent Be and four equivalent Hf atoms.
