The material structure described by RbAlF4 crystallizes in the tetragonal P4/mbm space group. Rb(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. Al(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form corner-sharing AlF6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are two inequivalent F sites. In the first F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Al(1) atoms. In the second F site, F(1) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Al(1) atom. is represented by the CIF card [CIF]
