The crystal structure described by RbBr3 crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded in a distorted square co-planar geometry to four equivalent Br(2) and eight equivalent Br(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to four equivalent Rb(1) atoms. In the second Br site, Br(2) is bonded in a square co-planar geometry to four equivalent Rb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
