TbCuTe2 crystallizes in the trigonal P-3m1 space group. Tb(1) is bonded to two equivalent Cu(1) and six equivalent Te(1) atoms to form a mixture of distorted corner and edge-sharing TbCu2Te6 octahedra. The corner-sharing octahedra are not tilted. Cu(1) is bonded in a 8-coordinate geometry to two equivalent Tb(1) and six equivalent Te(1) atoms. Te(1) is bonded in a 6-coordinate geometry to three equivalent Tb(1) and three equivalent Cu(1) atoms.
