description: Li3Zr4F19 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share a cornercorner with one LiF6 octahedra, corners with five ZrF7 pentagonal bipyramids, and edges with two ZrF7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 66°. There are a spread of Li–F bond distances ranging from 1.98–2.26 Å. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form distorted LiF6 octahedra that share corners with two LiF6 octahedra, corners with five ZrF7 pentagonal bipyramids, and an edgeedge with one ZrF7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 61–66°. There are a spread of Li–F bond distances ranging from 1.94–2.43 Å. In the third Li1+ site, Li1+ is bonded to six F1- atoms to form distorted LiF6 octahedra that share a cornercorner with one LiF6 octahedra, corners with five ZrF7 pentagonal bipyramids, an edgeedge with one LiF6 octahedra, and an edgeedge with one ZrF7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 61°. There are a spread of Li–F bond distances ranging from 1.94–2.31 Å. There are four inequivalent Zr4+ sites.

The corner-sharing octahedra tilt angles range from 8–44°. There are a spread of Zr–F bond distances ranging from 1.96–2.18 Å. In the third Zr4+ site, Zr4+ is bonded to seven F1- atoms to form ZrF7 pentagonal bipyramids that share corners with four LiF6 octahedra, corners with two ZrF7 pentagonal bipyramids, an edgeedge with one LiF6 octahedra, and an edgeedge with one ZrF7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 4–51°. There are a spread of Zr–F bond distances ranging from 2.00–2.21 Å. In the fourth Zr4+ site, Zr4+ is bonded to seven F1- atoms to form ZrF7 pentagonal bipyramids that share corners with three LiF6 octahedra, corners with three ZrF7 pentagonal bipyramids, an edgeedge with one LiF6 octahedra, and an edgeedge with one ZrF7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 8–47°. There are a spread of Zr–F bond distances ranging from 1.97–2.21 Å. There are nineteen inequivalent F1- sites.
