Rb3KCdCl6 crystallizes in the trigonal R-3c space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Cl(1) atoms. K(1) is bonded in a 6-coordinate geometry to six equivalent Cl(1) atoms. Cd(1) is bonded in an octahedral geometry to six equivalent Cl(1) atoms. Cl(1) is bonded to four equivalent Rb(1), one K(1), and one Cd(1) atom to form a mixture of distorted edge, corner, and face-sharing ClKRb4Cd octahedra. The corner-sharing octahedral tilt angles range from 0-65°.
