Materials Data on TaBe2 by Materials Project
Be2Ta is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Be is bonded to six equivalent Be and six equivalent Ta atoms to form a mixture of face, edge, and corner-sharing BeTa6Be6 cuboctahedra. All Be–Be bond lengths are 2.31 Å. All Be–Ta bond lengths are 2.70 Å. Ta is bonded in a 12-coordinate geometry to twelve equivalent Be and four equivalent Ta atoms. All Ta–Ta bond lengths are 2.82 Å.
