The compound described by DyTlTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Dy(1) is bonded to six equivalent Te(1) atoms to form DyTe6 octahedra that share corners with six equivalent Tl(1)Te6 octahedra, edges with six equivalent Dy(1)Te6 octahedra, and edges with six equivalent Tl(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 8°. Tl(1) is bonded to six equivalent Te(1) atoms to form distorted TlTe6 octahedra that share corners with six equivalent Dy(1)Te6 octahedra, edges with six equivalent Dy(1)Te6 octahedra, and edges with six equivalent Tl(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 8°. Te(1) is bonded to three equivalent Dy(1) and three equivalent Tl(1) atoms to form a mixture of distorted edge and corner-sharing TeDy3Tl3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
