Materials Data on Li5Yb4Sn5 by Materials Project

Li5Yb4Sn5 crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are five inequivalent Li sites. In the first Li site, Li is bonded in a distorted body-centered cubic geometry to four Yb and four Sn atoms. There are one shorter (2.94 Å) and three longer (2.95 Å) Li–Yb bond lengths. There are one shorter (2.79 Å) and three longer (2.96 Å) Li–Sn bond lengths. In the second Li site, Li is bonded in a body-centered cubic geometry to four Yb and four Sn atoms. There are one shorter (2.72 Å) and three longer (2.92 Å) Li–Yb bond lengths. There are one shorter (2.80 Å) and three longer (3.03 Å) Li–Sn bond lengths. In the third Li site, Li is bonded in a 4-coordinate geometry to four Yb and seven Sn atoms. There are three shorter (3.21 Å) and one longer (3.24 Å) Li–Yb bond lengths. There are a spread of Li–Sn bond distances ranging from 2.85–3.35 Å. In the fourth Li site, Li is bonded in a trigonal planar geometry to three equivalent Li, three equivalent Yb, and three equivalent Sn atoms. All Li–Li bond lengths are 3.04 Å. All Li–Yb bond lengths are 3.47 Å. All Li–Sn bond lengths are 2.83 Å. In the fifth Li site, Li is bonded in a 11-coordinate geometry to three equivalent Li, four Yb, and four Sn atoms. There are one shorter (3.15 Å) and three longer (3.36 Å) Li–Yb bond lengths. There are three shorter (3.07 Å) and one longer (3.26 Å) Li–Sn bond lengths. There are four inequivalent Yb sites. In the first Yb site, Yb is bonded in a 10-coordinate geometry to seven Li and six Sn atoms. There are three shorter (3.32 Å) and three longer (3.42 Å) Yb–Sn bond lengths.
