Materials Data on Ta3Be2 by Materials Project
Be2Ta3 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Be is bonded in a 9-coordinate geometry to one Be and eight Ta atoms. The Be–Be bond length is 2.10 Å. There are a spread of Be–Ta bond distances ranging from 2.54–2.62 Å. There are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a distorted square co-planar geometry to four equivalent Be atoms. In the second Ta site, Ta is bonded in a 6-coordinate geometry to six equivalent Be atoms.
