Title: Materials Data on K2ZrHF7 by Materials Project

Abstract

K2ZrHF7 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of K–F bond distances ranging from 2.68–3.06 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of K–F bond distances ranging from 2.68–3.17 Å. Zr4+ is bonded to seven F1- atoms to form edge-sharing ZrF7 pentagonal bipyramids. There are a spread of Zr–F bond distances ranging from 2.02–2.23 Å. H1+ is bonded in a linear geometry to two F1- atoms. There is one shorter (1.01 Å) and one longer (1.37 Å) H–F bond length. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to three K1+ and one Zr4+ atom. In the second F1- site, F1- is bonded in a 3-coordinate geometry to two K1+ and one Zr4+ atom. In the third F1- site, F1- is bonded in a 4-coordinate geometry to three K1+ and one Zr4+ atom. In the fourth F1- site, F1- is bonded in a 2-coordinate geometry tomore » one K1+, one Zr4+, and one H1+ atom. In the fifth F1- site, F1- is bonded in a 2-coordinate geometry to two K1+ and two equivalent Zr4+ atoms. In the sixth F1- site, F1- is bonded in a single-bond geometry to four K1+ and one H1+ atom. In the seventh F1- site, F1- is bonded in a 3-coordinate geometry to two K1+ and one Zr4+ atom.« less
