BeF2 is Low Tridymite-like structured and crystallizes in the trigonal R-3m space group. Be(1) is bonded to one F(1), one F(2), one F(3), and one F(4) atom to form corner-sharing BeF4 tetrahedra. There are four inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Be(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Be(1) atoms. In the third F site, F(3) is bonded in a bent 150 degrees geometry to two equivalent Be(1) atoms. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to two equivalent Be(1) atoms.
