The material structure described by ErDyTe2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Er(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form ErTe6 octahedra that share corners with six equivalent Er(1)Te6 octahedra, edges with four equivalent Er(1)Te6 octahedra, and edges with eight equivalent Dy(1)Te6 octahedra. The corner-sharing octahedra are not tilted. Dy(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form DyTe6 octahedra that share corners with six equivalent Dy(1)Te6 octahedra, edges with four equivalent Dy(1)Te6 octahedra, and edges with eight equivalent Er(1)Te6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to four equivalent Er(1) and two equivalent Dy(1) atoms to form TeDy2Er4 octahedra that share corners with six equivalent Te(1)Dy2Er4 octahedra, edges with four equivalent Te(1)Dy2Er4 octahedra, and edges with eight equivalent Te(2)Dy4Er2 octahedra. The corner-sharing octahedra are not tilted. In the second Te site, Te(2) is bonded to two equivalent Er(1) and four equivalent Dy(1) atoms to form TeDy4Er2 octahedra that share corners with six equivalent Te(2)Dy4Er2 octahedra, edges with four equivalent Te(2)Dy4Er2 octahedra, and edges with eight equivalent Te(1)Dy2Er4 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
