The compound described by TbCuTe2 crystallizes in the trigonal P3m1 space group. Tb(1) is bonded to three equivalent Te(1) and three equivalent Te(2) atoms to form distorted TbTe6 octahedra that share corners with six equivalent Cu(1)Te4 tetrahedra, edges with six equivalent Tb(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 Tb(1)Te6 octahedra, corners with six equivalent Cu(1)Te4 tetrahedra, and edges with three equivalent Tb(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 23-56°. 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 Tb(1) and one Cu(1) atom. In the second Te site, Te(2) is bonded to three equivalent Tb(1) and three equivalent Cu(1) atoms to form distorted edge-sharing TeTb3Cu3 octahedra. is represented by the CIF file [CIF]
