Materials Data on CsLi3I4 by Materials Project
CsLi3I4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a body-centered cubic geometry to eight I1- atoms. There are a spread of Cs–I bond distances ranging from 3.87–4.12 Å. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six I1- atoms. There are a spread of Cs–I bond distances ranging from 3.94–3.97 Å. There are six inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four I1- atoms to form corner-sharing LiI4 tetrahedra. There are a spread of Li–I bond distances ranging from 2.76–2.87 Å. In the second Li1+ site, Li1+ is bonded to four I1- atoms to form corner-sharing LiI4 tetrahedra. There are a spread of Li–I bond distances ranging from 2.75–2.80 Å. In the third Li1+ site, Li1+ is bonded to four I1- atoms to form corner-sharing LiI4 tetrahedra. There are two shorter (2.81 Å) and two longer (2.82 Å) Li–I bond lengths. In the fourth Li1+ site, Li1+ is bonded to four I1- atoms to form corner-sharing LiI4 tetrahedra. There are a spread of Li–I bond distances ranging from 2.77–2.81 Å. In the fifth Li1+ site, Li1+ is bonded to four I1- atoms to form corner-sharing LiI4 tetrahedra. There are a spread of Li–I bond distances ranging from 2.76–2.84 Å. In the sixth Li1+ site, Li1+ is bonded to four I1- atoms to form corner-sharing LiI4 tetrahedra. There are a spread of Li–I bond distances ranging from 2.77–2.82 Å.
