The crystal structure described by DyCuTe2 crystallizes in the trigonal P3m1 space group. Dy(1) is bonded to three equivalent Te(1) and three equivalent Te(2) atoms to form distorted DyTe6 octahedra that share corners with six equivalent Cu(1)Te4 tetrahedra, edges with six equivalent Dy(1)Te6 octahedra, and edges with three equivalent Cu(1)Te4 tetrahedra. Cu(1) is bonded to one Te(1) and three equivalent Te(2) atoms to form distorted CuTe4 tetrahedra that share corners with six equivalent Dy(1)Te6 octahedra, corners with six equivalent Cu(1)Te4 tetrahedra, and edges with three equivalent Dy(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 22-56°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to three equivalent Dy(1) and one Cu(1) atom. In the second Te site, Te(2) is bonded to three equivalent Dy(1) and three equivalent Cu(1) atoms to form distorted edge-sharing TeDy3Cu3 octahedra. is represented by the CIF card [CIF]
