The structure described by Nb3Tl crystallizes in the cubic Pm-3n space group. Nb(1) is bonded in a 14-coordinate geometry to ten equivalent Nb(1) and four equivalent Tl(1) atoms. Tl(1) is bonded to twelve equivalent Nb(1) atoms to form a mixture of edge and face-sharing TlNb12 cuboctahedra. is represented by the CIF file [CIF]
