Materials Data on ZrO3F5 by Materials Project

Abstract

(ZrF5)2(O2)3 crystallizes in the monoclinic C2 space group. The structure is two-dimensional and consists of eight trioxidane molecules and two ZrF5 sheets oriented in the (0, 0, 1) direction. In each ZrF5 sheet, Zr is bonded in a 8-coordinate geometry to eight F atoms. There are a spread of Zr–F bond distances ranging from 1.99–2.22 Å. There are five inequivalent F sites. In the first F site, F is bonded in a bent 120 degrees geometry to two equivalent Zr atoms. In the second F site, F is bonded in a single-bond geometry to one Zr atom. In the third F site, F is bonded in a single-bond geometry to one Zr atom. In the fourth F site, F is bonded in a bent 120 degrees geometry to two equivalent Zr atoms. In the fifth F site, F is bonded in a bent 120 degrees geometry to two equivalent Zr atoms.
