The material structure described by Be15Hf6Ni8 crystallizes in the cubic Fm-3m space group. There are three inequivalent Be sites. In the first Be site, Be(2) is bonded to four equivalent Be(1), four equivalent Hf(1), and four equivalent Ni(1) atoms to form a mixture of distorted face and corner-sharing BeHf4Be4Ni4 cuboctahedra. In the second Be site, Be(3) is bonded in a body-centered cubic geometry to eight equivalent Ni(1) atoms. In the third Be site, Be(1) is bonded in a distorted q6 geometry to three equivalent Be(1), three equivalent Be(2), three equivalent Hf(1), and three equivalent Ni(1) atoms. Hf(1) is bonded in a 12-coordinate geometry to four equivalent Be(1), four equivalent Be(2), and four equivalent Ni(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to one Be(3), three equivalent Be(1), three equivalent Be(2), and three equivalent Hf(1) atoms. is represented by the CIF file [CIF]
