Materials Data on Be2Nb by Materials Project
NbBe2 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 Nb atoms to form a mixture of face, edge, and corner-sharing BeBe6Nb6 cuboctahedra. All Be–Be bond lengths are 2.31 Å. All Be–Nb bond lengths are 2.71 Å. Nb is bonded in a 12-coordinate geometry to twelve equivalent Be and four equivalent Nb atoms. All Nb–Nb bond lengths are 2.83 Å.
