RbLiCl2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. Li(1) is bonded to two equivalent Cl(1) and two equivalent Cl(2) atoms to form corner-sharing LiCl4 tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent Rb(1) and two equivalent Li(1) atoms to form a mixture of distorted edge, face, and corner-sharing ClRb4Li2 octahedra. The corner-sharing octahedral tilt angles are 69°. In the second Cl site, Cl(2) is bonded in a distorted bent 120 degrees geometry to four equivalent Rb(1) and two equivalent Li(1) atoms.
RbLiCl2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. All Rb(1)-Cl(1) bond lengths are 3.31 Å. There are two shorter (3.32 Å) and two longer (3.70 Å) Rb(1)-Cl(2) bond lengths. Li(1) is bonded to two equivalent Cl(1) and two equivalent Cl(2) atoms to form corner-sharing LiCl4 tetrahedra. Both Li(1)-Cl(1) bond lengths are 2.34 Å. Both Li(1)-Cl(2) bond lengths are 2.41 Å.
