Materials Data on Be5Co by Materials Project
Be5Co 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 in a 4-coordinate geometry to twelve equivalent Be and four equivalent Co atoms. All Be–Be bond lengths are 2.39 Å. All Be–Co bond lengths are 2.50 Å. In the second Be site, Be is bonded to nine Be and three equivalent Co atoms to form a mixture of corner, edge, and face-sharing BeBe9Co3 cuboctahedra. There are three shorter (2.03 Å) and three longer (2.05 Å) Be–Be bond lengths. All Be–Co bond lengths are 2.39 Å. Co is bonded in a 12-coordinate geometry to sixteen Be atoms.
