Materials Data on Li8CaSn7 by Materials Project
Abstract
Li8CaSn7 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 Ca, and five Sn atoms. Both Li–Li bond lengths are 2.96 Å. The Li–Ca bond length is 3.16 Å. There are one shorter (2.77 Å) and four longer (2.96 Å) Li–Sn bond lengths. In the second Li site, Li is bonded in a 9-coordinate geometry to one Ca and six Sn atoms. The Li–Ca bond length is 3.22 Å. There are a spread of Li–Sn bond distances ranging from 2.88–3.32 Å. In the third Li site, Li is bonded in a 4-coordinate geometry to two equivalent Li and five Sn atoms. Both Li–Li bond lengths are 2.98 Å. There are a spread of Li–Sn bond distances ranging from 2.87–3.28 Å. In the fourth Li site, Li is bonded in a 3-coordinate geometry to one Li, one Ca, and five Sn atoms. The Li–Li bond length is 3.01 Å. The Li–Ca bond length is 3.21 Å. There are a spread of Li–Sn bond distances ranging from 2.81–3.08 Å. In the fifth Li site, Li is bondedmore »
