The material structure described by EuTlS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Eu(1) is bonded to six equivalent S(1) atoms to form EuS6 octahedra that share corners with six equivalent Tl(1)S6 octahedra, edges with six equivalent Eu(1)S6 octahedra, and edges with six equivalent Tl(1)S6 octahedra. The corner-sharing octahedral tilt angles are 9°. Tl(1) is bonded to six equivalent S(1) atoms to form distorted TlS6 octahedra that share corners with six equivalent Eu(1)S6 octahedra, edges with six equivalent Eu(1)S6 octahedra, and edges with six equivalent Tl(1)S6 octahedra. The corner-sharing octahedral tilt angles are 9°. S(1) is bonded to three equivalent Eu(1) and three equivalent Tl(1) atoms to form a mixture of distorted corner and edge-sharing SEu3Tl3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
