RbBe3ZnF9 crystallizes in the hexagonal P-6c2 space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent F(1) atoms. Be(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form BeF4 tetrahedra that share corners with two equivalent Zn(1)F6 octahedra and corners with two equivalent Be(1)F4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. Zn(1) is bonded to six equivalent F(1) atoms to form ZnF6 octahedra that share corners with six equivalent Be(1)F4 tetrahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one Rb(1), one Be(1), and one Zn(1) atom. In the second F site, F(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Be(1) atoms.
RbBe3ZnF9 crystallizes in the hexagonal P-6c2 space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent F(1) atoms. All Rb(1)-F(1) bond lengths are 2.88 Å. Be(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form BeF4 tetrahedra that share corners with two equivalent Zn(1)F6 octahedra and corners with two equivalent Be(1)F4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. Both Be(1)-F(1) bond lengths are 1.55 Å. There is one shorter (1.59 Å) and one longer (1.60 Å) Be(1)-F(2) bond length. Zn(1) is bonded to six equivalent F(1) atoms to form ZnF6 octahedra that share corners with six equivalent Be(1)F4 tetrahedra. All Zn(1)-F(1) bond lengths are 2.06 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one Rb(1), one Be(1), and one Zn(1) atom.
