Title: Materials Data on LiSn4Au3 by Materials Project

Abstract

LiAu3Sn4 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Li is bonded to four Au and six Sn atoms to form distorted LiSn6Au4 tetrahedra that share corners with three equivalent SnAu4 tetrahedra and faces with six equivalent LiSn6Au4 tetrahedra. There are one shorter (2.77 Å) and three longer (2.83 Å) Li–Au bond lengths. There are three shorter (3.18 Å) and three longer (3.22 Å) Li–Sn bond lengths. There are three inequivalent Au sites. In the first Au site, Au is bonded in a 8-coordinate geometry to one Li, one Au, and six Sn atoms. The Au–Au bond length is 2.93 Å. There are three shorter (2.84 Å) and three longer (2.96 Å) Au–Sn bond lengths. In the second Au site, Au is bonded in a 8-coordinate geometry to one Au and seven Sn atoms. There are a spread of Au–Sn bond distances ranging from 2.81–3.10 Å. In the third Au site, Au is bonded in a body-centered cubic geometry to three equivalent Li and five Sn atoms. There are a spread of Au–Sn bond distances ranging from 2.74–2.85 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometrymore » to three equivalent Li and four Au atoms. In the second Sn site, Sn is bonded to four Au atoms to form SnAu4 tetrahedra that share corners with three equivalent LiSn6Au4 tetrahedra and corners with six equivalent SnAu4 tetrahedra. In the third Sn site, Sn is bonded in a 4-coordinate geometry to three equivalent Li and four Au atoms. In the fourth Sn site, Sn is bonded in a 6-coordinate geometry to six Au atoms.« less
