The structure described by RbLiBr2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent Br(1) and four equivalent Br(2) atoms. Li(1) is bonded to two equivalent Br(1) and two equivalent Br(2) atoms to form corner-sharing LiBr4 tetrahedra. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 2-coordinate geometry to four equivalent Rb(1) and two equivalent Li(1) atoms. In the second Br site, Br(2) is bonded to four equivalent Rb(1) and two equivalent Li(1) atoms to form a mixture of distorted corner, edge, and face-sharing BrRb4Li2 octahedra. The corner-sharing octahedral tilt angles are 67°. is represented by the CIF file [CIF]
