Materials Data on Li2Tl by Materials Project
Li2Tl crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two Li2Tl sheets oriented in the (0, 1, 0) direction. there are two inequivalent Li sites. In the first Li site, Li is bonded to four equivalent Tl atoms to form a mixture of distorted edge and corner-sharing LiTl4 tetrahedra. There are two shorter (2.84 Å) and two longer (2.87 Å) Li–Tl bond lengths. In the second Li site, Li is bonded in a 2-coordinate geometry to two equivalent Tl atoms. Both Li–Tl bond lengths are 2.99 Å. Tl is bonded in a 6-coordinate geometry to six Li atoms.
