Materials Data on HfBe13 by Materials Project
Be13Hf crystallizes in the cubic Fm-3c space group. The structure is three-dimensional. there are two inequivalent Be sites. In the first Be site, Be is bonded to ten Be and two equivalent Hf atoms to form a mixture of distorted edge, face, and corner-sharing BeHf2Be10 cuboctahedra. There are a spread of Be–Be bond distances ranging from 2.11–2.31 Å. Both Be–Hf bond lengths are 2.92 Å. In the second Be site, Be is bonded to twelve equivalent Be atoms to form a mixture of face and corner-sharing BeBe12 cuboctahedra. Hf is bonded in a 1-coordinate geometry to twenty-four equivalent Be atoms.
