NbO12TlO2 is Cuprite-derived structured and crystallizes in the cubic Fd-3m space group. The structure consists of eight NbO12 clusters inside a TlO2 framework. In each NbO12 cluster, Nb(1) is bonded in a cuboctahedral geometry to twelve equivalent O(1) atoms. O(1) is bonded in a 3-coordinate geometry to one Nb(1) and two equivalent O(1) atoms. In the TlO2 framework, Tl(1) is bonded to four equivalent O(2) atoms to form corner-sharing TlO4 tetrahedra. O(2) is bonded in a linear geometry to two equivalent Tl(1) atoms.
