Materials Data on NaTl by Materials Project

Abstract

NaTl crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Na is bonded in a 11-coordinate geometry to four equivalent Na and seven Tl atoms. There are three shorter (3.46 Å) and one longer (3.55 Å) Na–Na bond lengths. There are one shorter (3.39 Å) and six longer (3.54 Å) Na–Tl bond lengths. There are two inequivalent Tl sites. In the first Tl site, Tl is bonded in a 9-coordinate geometry to six equivalent Na and three equivalent Tl atoms. All Tl–Tl bond lengths are 3.06 Å. In the second Tl site, Tl is bonded in a 11-coordinate geometry to eight equivalent Na and three equivalent Tl atoms.
