Materials Data on Be2BO3F by Materials Project
Be2BO3F crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Be2+ is bonded to three equivalent O2- and one F1- atom to form corner-sharing BeO3F tetrahedra. All Be–O bond lengths are 1.63 Å. The Be–F bond length is 1.59 Å. B3+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All B–O bond lengths are 1.38 Å. O2- is bonded in a trigonal planar geometry to two equivalent Be2+ and one B3+ atom. F1- is bonded in a linear geometry to two equivalent Be2+ atoms.
