Materials Data on Li8EuSn7 by Materials Project
Abstract
Li8EuSn7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are five inequivalent Li sites. In the first Li site, Li is bonded in a 8-coordinate geometry to two equivalent Li, one Eu, and five Sn atoms. Both Li–Li bond lengths are 2.96 Å. The Li–Eu bond length is 3.21 Å. There are one shorter (2.78 Å) and four longer (2.97 Å) Li–Sn bond lengths. In the second Li site, Li is bonded to eight Li and four equivalent Sn atoms to form LiLi8Sn4 cuboctahedra that share corners with two equivalent LiLi8Sn4 cuboctahedra, edges with four equivalent SnLi8Eu2Sn2 cuboctahedra, faces with two equivalent LiLi8Sn4 cuboctahedra, and faces with four equivalent SnLi8Eu2Sn2 cuboctahedra. There are two shorter (2.93 Å) and four longer (2.98 Å) Li–Li bond lengths. All Li–Sn bond lengths are 3.22 Å. In the third Li site, Li is bonded in a 3-coordinate geometry to two equivalent Li, one Eu, and six Sn atoms. Both Li–Li bond lengths are 3.20 Å. The Li–Eu bond length is 3.27 Å. There are a spread of Li–Sn bond distances ranging from 2.86–3.30 Å. In the fourth Li site, Li is bonded in a 3-coordinate geometry to one Li, onemore »
