Be2HfBi is alpha bismuth trifluoride-derived structured and crystallizes in the cubic F-43m space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded to four equivalent Hf(1) atoms to form corner-sharing BeHf4 tetrahedra. In the second Be site, Be(2) is bonded to four equivalent Bi(1) atoms to form corner-sharing BeBi4 tetrahedra. Hf(1) is bonded in a body-centered cubic geometry to four equivalent Be(1) and four equivalent Bi(1) atoms. Bi(1) is bonded in a body-centered cubic geometry to four equivalent Be(2) and four equivalent Hf(1) atoms.
