KBeF3 crystallizes in the orthorhombic P2_12_12_1 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent F(3), three equivalent F(1), and three equivalent F(2) atoms. Be(1) is bonded to one F(1), one F(2), and two equivalent F(3) atoms to form corner-sharing BeF4 tetrahedra. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Be(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Be(1) atom. In the third F site, F(3) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1) and two equivalent Be(1) atoms.
KBeF3 crystallizes in the orthorhombic P2_12_12_1 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent F(3), three equivalent F(1), and three equivalent F(2) atoms. There is one shorter (2.81 Å) and one longer (3.12 Å) K(1)-F(3) bond length. There are a spread of K(1)-F(1) bond distances ranging from 2.60-2.81 Å. There are a spread of K(1)-F(2) bond distances ranging from 2.63-2.84 Å. Be(1) is bonded to one F(1), one F(2), and two equivalent F(3) atoms to form corner-sharing BeF4 tetrahedra. The Be(1)-F(1) bond length is 1.52 Å. The Be(1)-F(2) bond length is 1.52 Å. Both Be(1)-F(3) bond lengths are 1.60 Å. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Be(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Be(1) atom. In the third F site, F(3) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1) and two equivalent Be(1) atoms.
