Materials Data on Tl3Sn by Materials Project
Tl3Sn crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tl is bonded in a 12-coordinate geometry to eight equivalent Tl and four equivalent Sn atoms. There are a spread of Tl–Tl bond distances ranging from 3.44–3.60 Å. There are two shorter (3.46 Å) and two longer (3.52 Å) Tl–Sn bond lengths. Sn is bonded to twelve equivalent Tl atoms to form a mixture of corner and face-sharing SnTl12 cuboctahedra.
