The structure described by RbLaSe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded to six equivalent Se(1) atoms to form distorted RbSe6 octahedra that share corners with six equivalent La(1)Se6 octahedra, edges with six equivalent Rb(1)Se6 octahedra, and edges with six equivalent La(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 10°. La(1) is bonded to six equivalent Se(1) atoms to form LaSe6 octahedra that share corners with six equivalent Rb(1)Se6 octahedra, edges with six equivalent Rb(1)Se6 octahedra, and edges with six equivalent La(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 10°. Se(1) is bonded to three equivalent Rb(1) and three equivalent La(1) atoms to form a mixture of edge and corner-sharing SeRb3La3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
