The structure described by Dy(CuTe)3 crystallizes in the trigonal R-3 space group. Dy(1) is bonded to six equivalent Te(1) atoms to form distorted DyTe6 octahedra that share corners with twelve equivalent Cu(1)Te4 tetrahedra, edges with three equivalent Dy(1)Te6 octahedra, and edges with six equivalent Cu(1)Te4 tetrahedra. Cu(1) is bonded to four equivalent Te(1) atoms to form distorted CuTe4 tetrahedra that share corners with four equivalent Dy(1)Te6 octahedra, corners with six equivalent Cu(1)Te4 tetrahedra, edges with two equivalent Dy(1)Te6 octahedra, and edges with three equivalent Cu(1)Te4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-59°. Te(1) is bonded in a 6-coordinate geometry to two equivalent Dy(1) and four equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
