The compound described by Tb3Te is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to four equivalent Tb(1), four equivalent Tb(2), and four equivalent Te(1) atoms to form distorted TbTb8Te4 cuboctahedra that share corners with twelve equivalent Tb(1)Tb8Te4 cuboctahedra, edges with eight equivalent Tb(1)Tb8Te4 cuboctahedra, edges with eight equivalent Te(1)Tb12 cuboctahedra, faces with four equivalent Te(1)Tb12 cuboctahedra, and faces with ten equivalent Tb(1)Tb8Te4 cuboctahedra. In the second Tb site, Tb(2) is bonded in a square co-planar geometry to eight equivalent Tb(1) and four equivalent Te(1) atoms. Te(1) is bonded to four equivalent Tb(2) and eight equivalent Tb(1) atoms to form TeTb12 cuboctahedra that share corners with four equivalent Te(1)Tb12 cuboctahedra, edges with eight equivalent Te(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Tb8Te4 cuboctahedra, faces with four equivalent Te(1)Tb12 cuboctahedra, and faces with eight equivalent Tb(1)Tb8Te4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
