Title: Materials Data on Rb2LiTaS4 by Materials Project

Abstract

Rb2LiTaS4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to eight S2- atoms to form distorted RbS8 hexagonal bipyramids that share corners with two equivalent RbS8 hexagonal bipyramids, corners with four TaS4 tetrahedra, a cornercorner with one LiS5 trigonal bipyramid, edges with three RbS8 hexagonal bipyramids, edges with three equivalent RbS7 pentagonal bipyramids, edges with two TaS4 tetrahedra, edges with three equivalent LiS4 tetrahedra, an edgeedge with one LiS5 trigonal bipyramid, and a faceface with one RbS8 hexagonal bipyramid. There are a spread of Rb–S bond distances ranging from 3.37–3.73 Å. In the second Rb1+ site, Rb1+ is bonded to eight S2- atoms to form distorted RbS8 hexagonal bipyramids that share corners with two equivalent RbS8 hexagonal bipyramids, corners with two equivalent RbS7 pentagonal bipyramids, corners with two equivalent LiS4 tetrahedra, corners with two TaS4 tetrahedra, edges with two equivalent RbS8 hexagonal bipyramids, an edgeedge with one RbS7 pentagonal bipyramid, an edgeedge with one LiS4 tetrahedra, edges with three TaS4 tetrahedra, edges with three equivalent LiS5 trigonal bipyramids, and a faceface with one RbS8 hexagonal bipyramid. There are a spread of Rb–S bondmore » distances ranging from 3.39–3.85 Å.

There are a spread of Ta–S bond distances ranging from 2.28–2.30 Å. There are eight inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinate geometry to three Rb1+, two equivalent Li1+, and one Ta5+ atom. In the second S2- site, S2- is bonded in a 3-coordinate geometry to two Rb1+, two equivalent Li1+, and one Ta5+ atom. In the third S2- site, S2- is bonded to four Rb1+, one Li1+, and one Ta5+ atom to form distorted corner-sharing SRb4LiTa octahedra. The corner-sharing octahedra tilt angles range from 5–69°. In the fourth S2- site, S2- is bonded in a 3-coordinate geometry to three Rb1+, two equivalent Li1+, and one Ta5+ atom. In the fifth S2- site, S2- is bonded to five Rb1+ and one Ta5+ atom to form distorted SRb5Ta octahedra that share corners with four SRb4LiTa octahedra and edges with two equivalent SRb5Ta octahedra. The corner-sharing octahedra tilt angles range from 20–69°. In the sixth S2- site, S2- is bonded in a 2-coordinate geometry to four Rb1+, one Li1+, and one Ta5+ atom. In the seventh S2- site, S2- is bonded in a 6-coordinate geometry to five Rb1+ and one Ta5+ atom.
