The compound described by KBe2BO3F2 crystallizes in the trigonal R32 space group. K(1) is bonded in a 6-coordinate geometry to six equivalent F(1) atoms. 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 distorted single-bond geometry to three equivalent K(1) and one Be(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
