LaNb3Te is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. La(1) is bonded to twelve equivalent Nb(1) atoms to form distorted LaNb12 cuboctahedra that share corners with twelve equivalent La(1)Nb12 cuboctahedra, faces with six equivalent La(1)Nb12 cuboctahedra, and faces with eight equivalent Te(1)Nb6 octahedra. There are a spread of La(1)-Nb(1) bond distances ranging from 3.16-4.09 Å. Nb(1) is bonded in a 1-coordinate geometry to four equivalent La(1) and two equivalent Te(1) atoms. There is one shorter (2.23 Å) and one longer (2.89 Å) Nb(1)-Te(1) bond length. Te(1) is bonded to six equivalent Nb(1) atoms to form TeNb6 octahedra that share corners with six equivalent Te(1)Nb6 octahedra and faces with eight equivalent La(1)Nb12 cuboctahedra. The corner-sharing octahedra are not tilted.
