Materials Data on YBe13 by Materials Project

Be13Y 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 twelve equivalent Be atoms to form a mixture of corner and face-sharing BeBe12 cuboctahedra. All Be–Be bond lengths are 2.14 Å. In the second Be site, Be is bonded to ten Be and two equivalent Y atoms to form distorted BeY2Be10 cuboctahedra that share corners with twenty-eight BeBe12 cuboctahedra, edges with eight equivalent BeY2Be10 cuboctahedra, and faces with twenty-five BeBe12 cuboctahedra. There are a spread of Be–Be bond distances ranging from 2.22–2.32 Å. Both Be–Y bond lengths are 2.99 Å. Y is bonded in a 1-coordinate geometry to twenty-four equivalent Be atoms.
