CsBeF3 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent F(1) and six equivalent F(2) atoms. Be(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form corner-sharing BeF4 tetrahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Cs(1) and two equivalent Be(1) atoms. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one Be(1) atom.
CsBeF3 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent F(1) and six equivalent F(2) atoms. Both Cs(1)-F(1) bond lengths are 3.36 Å. There are a spread of Cs(1)-F(2) bond distances ranging from 2.96-3.06 Å. Be(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form corner-sharing BeF4 tetrahedra. There is one shorter (1.59 Å) and one longer (1.61 Å) Be(1)-F(1) bond length. Both Be(1)-F(2) bond lengths are 1.52 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Cs(1) and two equivalent Be(1) atoms. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one Be(1) atom.
