Materials Data on ZnWF5 by Materials Project

Abstract

WZnF5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. W3+ is bonded to six F1- atoms to form corner-sharing WF6 octahedra. The corner-sharing octahedral tilt angles are 36°. There are a spread of W–F bond distances ranging from 2.11–2.13 Å. Zn2+ is bonded in a 4-coordinate geometry to five F1- atoms. There are a spread of Zn–F bond distances ranging from 1.93–2.55 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 120 degrees geometry to one W3+ and one Zn2+ atom. In the second F1- site, F1- is bonded in a 3-coordinate geometry to one W3+ and two equivalent Zn2+ atoms. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to one W3+ and one Zn2+ atom. In the fourth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one W3+ and one Zn2+ atom. In the fifth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent W3+ atoms.
