Materials Data on Be2Nb3 by Materials Project
Be2Nb3 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 Nb atoms. The Be–Be bond length is 2.09 Å. There are a spread of Be–Nb bond distances ranging from 2.55–2.63 Å. There are two inequivalent Nb sites. In the first Nb site, Nb is bonded in a distorted square co-planar geometry to four equivalent Be atoms. In the second Nb site, Nb is bonded in a 6-coordinate geometry to six equivalent Be atoms.
