Materials Data on Na3TlO6 by Materials Project
NaNa2TlO4O2 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two sodium molecules; four water molecules; and one Na2TlO4 sheet oriented in the (0, 0, 1) direction. In the Na2TlO4 sheet, Na is bonded in a linear geometry to two equivalent O atoms. Both Na–O bond lengths are 2.14 Å. Tl is bonded in a distorted rectangular see-saw-like geometry to four equivalent O atoms. All Tl–O bond lengths are 2.08 Å. O is bonded in a linear geometry to one Na and one Tl atom.
