Materials Data on Be2Si by Materials Project
Be2Si is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Be2+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing BeSi4 tetrahedra. All Be–Si bond lengths are 2.29 Å. Si4- is bonded in a body-centered cubic geometry to eight equivalent Be2+ atoms.
