The crystal structure described by SmLaS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sm(1) is bonded to six equivalent S(1) atoms to form SmS6 octahedra that share corners with six equivalent La(1)S6 octahedra, edges with six equivalent Sm(1)S6 octahedra, and edges with six equivalent La(1)S6 octahedra. The corner-sharing octahedral tilt angles are 3°. La(1) is bonded to six equivalent S(1) atoms to form LaS6 octahedra that share corners with six equivalent Sm(1)S6 octahedra, edges with six equivalent Sm(1)S6 octahedra, and edges with six equivalent La(1)S6 octahedra. The corner-sharing octahedral tilt angles are 3°. S(1) is bonded to three equivalent Sm(1) and three equivalent La(1) atoms to form a mixture of edge and corner-sharing SLa3Sm3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
