The compound described by Rb2CdCl4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded in a 9-coordinate geometry to four equivalent Cl(1) and five equivalent Cl(2) atoms. Cd(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form corner-sharing CdCl6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded to five equivalent Rb(1) and one Cd(1) atom to form distorted ClRb5Cd octahedra that share corners with five equivalent Cl(2)Rb5Cd octahedra, corners with twelve equivalent Cl(1)Rb4Cd2 octahedra, edges with eight equivalent Cl(2)Rb5Cd octahedra, and faces with four equivalent Cl(1)Rb4Cd2 octahedra. The corner-sharing octahedral tilt angles range from 0-54°. In the second Cl site, Cl(1) is bonded to four equivalent Rb(1) and two equivalent Cd(1) atoms to form ClRb4Cd2 octahedra that share corners with two equivalent Cl(1)Rb4Cd2 octahedra, corners with twelve equivalent Cl(2)Rb5Cd octahedra, edges with two equivalent Cl(1)Rb4Cd2 octahedra, faces with four equivalent Cl(1)Rb4Cd2 octahedra, and faces with four equivalent Cl(2)Rb5Cd octahedra. The corner-sharing octahedral tilt angles range from 0-54°. is represented by the CIF file [CIF]
