Materials Data on ZrPb2F8 by Materials Project

Abstract

Pb2ZrF8 crystallizes in the orthorhombic Pnma 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 2.07–2.24 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Pb–F bond distances ranging from 2.47–2.96 Å. In the second Pb2+ site, Pb2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Pb–F bond distances ranging from 2.47–3.17 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one Zr4+ and three Pb2+ atoms. In the second F1- site, F1- is bonded in a 2-coordinate geometry to one Zr4+ and three Pb2+ atoms. In the third F1- site, F1- is bonded in a distorted single-bond geometry to one Zr4+ and three Pb2+ atoms. In the fourth F1- site, F1- is bonded in a 1-coordinate geometry to one Zr4+ and three Pb2+ atoms. In the fifth F1- site, F1- is bonded in a 3-coordinate geometry to one Zr4+ and two Pb2+ atoms.
