The material structure described by Be2BO3F crystallizes in the trigonal R-3c space group. Be(1) is bonded to three equivalent O(1) and one F(1) atom to form corner-sharing BeO3F tetrahedra. B(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent Be(1) and one B(1) atom. F(1) is bonded in a linear geometry to two equivalent Be(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
