Materials Data on LiCu2Sn by Materials Project
Cu2LiSn crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li is bonded to six equivalent Cu and six equivalent Sn atoms to form a mixture of distorted corner and face-sharing LiCu6Sn6 cuboctahedra. All Li–Cu bond lengths are 2.57 Å. All Li–Sn bond lengths are 3.13 Å. Cu is bonded in a 3-coordinate geometry to three equivalent Li and four equivalent Sn atoms. There are one shorter (2.59 Å) and three longer (2.77 Å) Cu–Sn bond lengths. Sn is bonded in a 2-coordinate geometry to six equivalent Li and eight equivalent Cu atoms.
