LaTi2TlO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. La(1) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent Tl(1)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. Ti(1) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra, faces with four equivalent La(1)O12 cuboctahedra, and faces with four equivalent Tl(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Tl(1) is bonded to twelve equivalent O(1) atoms to form TlO12 cuboctahedra that share corners with twelve equivalent Tl(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. O(1) is bonded in a distorted linear geometry to two equivalent La(1), two equivalent Ti(1), and two equivalent Tl(1) atoms.
