Materials Data on ZnWF4 by Materials Project
WZnF4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent W2+ sites. In the first W2+ site, W2+ is bonded in a square co-planar geometry to four F1- atoms. All W–F bond lengths are 2.03 Å. In the second W2+ site, W2+ is bonded in a square co-planar geometry to four F1- atoms. There are one shorter (2.02 Å) and three longer (2.03 Å) W–F bond lengths. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Zn–F bond distances ranging from 2.53–2.60 Å. In the second Zn2+ site, Zn2+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Zn–F bond distances ranging from 2.49–2.60 Å. There are eight inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the third F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the fourth F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the fifth F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the sixth F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the seventh F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms. In the eighth F1- site, F1- is bonded in a distorted trigonal planar geometry to one W2+ and two Zn2+ atoms.
