RbSmTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded to six equivalent Te(1) atoms to form distorted RbTe6 octahedra that share corners with six equivalent Sm(1)Te6 octahedra, edges with six equivalent Rb(1)Te6 octahedra, and edges with six equivalent Sm(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 10°. Sm(1) is bonded to six equivalent Te(1) atoms to form SmTe6 octahedra that share corners with six equivalent Rb(1)Te6 octahedra, edges with six equivalent Rb(1)Te6 octahedra, and edges with six equivalent Sm(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 10°. Te(1) is bonded to three equivalent Rb(1) and three equivalent Sm(1) atoms to form a mixture of corner and edge-sharing TeRb3Sm3 octahedra. The corner-sharing octahedra are not tilted.
