Materials Data on TlO2 by Materials Project

TlO2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent Tl sites. In the first Tl site, Tl is bonded to six O atoms to form edge-sharing TlO6 octahedra. There are four shorter (2.24 Å) and two longer (2.32 Å) Tl–O bond lengths. In the second Tl site, Tl is bonded to six O atoms to form a mixture of edge and corner-sharing TlO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Tl–O bond distances ranging from 2.21–2.36 Å. There are three inequivalent O sites. In the first O site, O is bonded in a trigonal planar geometry to three equivalent Tl atoms. In the second O site, O is bonded in a trigonal non-coplanar geometry to three Tl atoms. In the third O site, O is bonded in a trigonal non-coplanar geometry to three Tl atoms.

Materials Data on Tl(C2O5)2 by Materials Project

TlO2(CO2)4 is Cyanogen Chloride-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of eight carbon dioxide molecules and two TlO2 clusters. In each TlO2 cluster, Tl is bonded in a 1-coordinate geometry to two O atoms. There are one shorter (2.43 Å) and one longer (2.52 Å) Tl–O bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to one Tl and one O atom. The O–O bond length is 1.35 Å. In the second O site, O is bonded in a distorted L-shaped geometry to one Tl and one O atom.

Materials Data on NbTlO14 by Materials Project

NbO12TlO2 is Cuprite-derived structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional and consists of eight NbO12 clusters and one TlO2 framework. In each NbO12 cluster, Nb is bonded in a cuboctahedral geometry to twelve equivalent O atoms. All Nb–O bond lengths are 2.21 Å. O is bonded in a 1-coordinate geometry to one Nb and two equivalent O atoms. Both O–O bond lengths are 1.82 Å. In the TlO2 framework, Tl is bonded to four equivalent O atoms to form corner-sharing TlO4 tetrahedra. All Tl–O bond lengths are 2.36 Å. O is bonded in a linear geometry to two equivalent Tl atoms.
