Materials Data on Na5Zr2F13 by Materials Project
Na5Zr2F13 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six F1- atoms to form distorted NaF6 pentagonal pyramids that share corners with four equivalent ZrF7 pentagonal bipyramids, an edgeedge with one ZrF7 pentagonal bipyramid, and edges with two equivalent NaF6 pentagonal pyramids. There are a spread of Na–F bond distances ranging from 2.33–2.40 Å. In the second Na1+ site, Na1+ is bonded in a body-centered cubic geometry to eight F1- atoms. There are a spread of Na–F bond distances ranging from 2.42–2.54 Å. In the third Na1+ site, Na1+ is bonded in a body-centered cubic geometry to eight F1- atoms. There are four shorter (2.33 Å) and four longer (2.63 Å) Na–F bond lengths. Zr4+ is bonded to seven F1- atoms to form distorted ZrF7 pentagonal bipyramids that share a cornercorner with one ZrF7 pentagonal bipyramid, corners with four equivalent NaF6 pentagonal pyramids, and an edgeedge with one NaF6 pentagonal pyramid. There are a spread of Zr–F bond distances ranging from 2.08–2.16 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded to three Na1+ and one Zr4+ atom to form a mixture of distorted corner and edge-sharing FNa3Zr tetrahedra. In the second F1- site, F1- is bonded in a 4-coordinate geometry to three Na1+ and one Zr4+ atom. In the third F1- site, F1- is bonded to three Na1+ and one Zr4+ atom to form a mixture of corner and edge-sharing FNa3Zr tetrahedra. In the fourth F1- site, F1- is bonded in a linear geometry to two equivalent Zr4+ atoms.
