Materials Data on Li2SnO6 by Materials Project
Li2SnO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Li–O bond distances ranging from 1.98–2.32 Å. Sn is bonded in an octahedral geometry to six O atoms. There are two shorter (2.08 Å) and four longer (2.11 Å) Sn–O bond lengths. There are three inequivalent O sites. In the first O site, O is bonded in a trigonal non-coplanar geometry to two equivalent Li and one Sn atom. In the second O site, O is bonded in a distorted T-shaped geometry to two equivalent Li and one Sn atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Li and one Sn atom.
