Materials Data on CsLi2BS3 by Materials Project

Abstract

CsLi2BS3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Cs–S bond distances ranging from 3.52–3.95 Å. Li1+ is bonded to four S2- atoms to form a mixture of distorted edge and corner-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.40–2.52 Å. B3+ is bonded in a trigonal planar geometry to three S2- atoms. There is two shorter (1.82 Å) and one longer (1.85 Å) B–S bond length. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 3-coordinate geometry to four equivalent Cs1+, two equivalent Li1+, and one B3+ atom. In the second S2- site, S2- is bonded in a 6-coordinate geometry to one Cs1+, four equivalent Li1+, and one B3+ atom.
