Materials Data on ZrH6(OF3)2 by Materials Project

Abstract

ZrH6(OF3)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Zr4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Zr–F bond distances ranging from 2.06–2.23 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.02 Å. The H–F bond length is 1.52 Å. In the second H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.02 Å. The H–F bond length is 1.55 Å. In the third H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.03 Å. The H–F bond length is 1.43 Å. O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to one Zr4+ and two H1+ atoms. In the second F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Zr4+ atoms. In the third F1- site, F1- is bonded in a distorted bent 120 degrees geometry to one Zr4+ and one H1+ atom.
