Materials Data on Li2BiS2 by Materials Project

Li2BiS2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Li1+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.37–2.50 Å. Bi2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Bi–S bond lengths are 2.84 Å. S2- is bonded in a 6-coordinate geometry to four equivalent Li1+ and two equivalent Bi2+ atoms.

Li2BiS2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four S2- atoms to form a mixture of corner and edge-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.38–2.54 Å. In the second Li1+ site, Li1+ is bonded to four S2- atoms to form a mixture of corner and edge-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.38–2.53 Å. Bi2+ is bonded in a rectangular see-saw-like geometry to four S2- atoms. There are a spread of Bi–S bond distances ranging from 2.81–2.84 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to four Li1+ and two equivalent Bi2+ atoms. In the second S2- site, S2- is bonded in a 6-coordinate geometry to four Li1+ and two equivalent Bi2+ atoms.

Materials Data on Li2BiS2 by Materials Project

Li2BiS2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Li1+ is bonded to four equivalent S2- atoms to form a mixture of corner and edge-sharing LiS4 tetrahedra. There are two shorter (2.37 Å) and two longer (2.51 Å) Li–S bond lengths. Bi2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Bi–S bond lengths are 2.83 Å. S2- is bonded in a 6-coordinate geometry to four equivalent Li1+ and two equivalent Bi2+ atoms.
