The material structure described by VTl3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. V(1) is bonded to four equivalent Tl(2) and eight equivalent Tl(1) atoms to form VTl12 cuboctahedra that share corners with four equivalent V(1)Tl12 cuboctahedra, corners with eight equivalent Tl(2)Tl8V4 cuboctahedra, edges with eight equivalent V(1)Tl12 cuboctahedra, edges with sixteen equivalent Tl(1)Tl8V4 cuboctahedra, faces with four equivalent V(1)Tl12 cuboctahedra, faces with six equivalent Tl(2)Tl8V4 cuboctahedra, and faces with eight equivalent Tl(1)Tl8V4 cuboctahedra. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded to four equivalent V(1), four equivalent Tl(1), and four equivalent Tl(2) atoms to form TlTl8V4 cuboctahedra that share corners with twelve equivalent Tl(1)Tl8V4 cuboctahedra, edges with eight equivalent V(1)Tl12 cuboctahedra, edges with eight equivalent Tl(1)Tl8V4 cuboctahedra, edges with eight equivalent Tl(2)Tl8V4 cuboctahedra, faces with four equivalent V(1)Tl12 cuboctahedra, faces with four equivalent Tl(2)Tl8V4 cuboctahedra, and faces with ten equivalent Tl(1)Tl8V4 cuboctahedra. In the second Tl site, Tl(2) is bonded to four equivalent V(1) and eight equivalent Tl(1) atoms to form TlTl8V4 cuboctahedra that share corners with four equivalent Tl(2)Tl8V4 cuboctahedra, corners with eight equivalent V(1)Tl12 cuboctahedra, edges with eight equivalent Tl(2)Tl8V4 cuboctahedra, edges with sixteen equivalent Tl(1)Tl8V4 cuboctahedra, faces with four equivalent Tl(2)Tl8V4 cuboctahedra, faces with six equivalent V(1)Tl12 cuboctahedra, and faces with eight equivalent Tl(1)Tl8V4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
