The structure described by RbKCl2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded to six equivalent Cl(1) atoms to form RbCl6 octahedra that share corners with six equivalent K(1)Cl6 octahedra, edges with six equivalent Rb(1)Cl6 octahedra, and edges with six equivalent K(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 3°. K(1) is bonded to six equivalent Cl(1) atoms to form KCl6 octahedra that share corners with six equivalent Rb(1)Cl6 octahedra, edges with six equivalent Rb(1)Cl6 octahedra, and edges with six equivalent K(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 3°. Cl(1) is bonded to three equivalent Rb(1) and three equivalent K(1) atoms to form a mixture of edge and corner-sharing ClK3Rb3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
