Materials Data on Na2TlAs by Materials Project
Na2TlAs crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Na2TlAs ribbons oriented in the (1, 0, 0) direction. Na1+ is bonded in a linear geometry to one Tl1+ and one As3- atom. The Na–Tl bond length is 3.26 Å. The Na–As bond length is 2.88 Å. Tl1+ is bonded in a linear geometry to two equivalent Na1+ atoms. As3- is bonded in a linear geometry to two equivalent Na1+ atoms.
