Materials Data on CrF4 by Materials Project

Abstract

CrF4 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of two tetrafluorochromium molecules. Cr4+ is bonded in a square co-planar geometry to four F1- atoms. There are a spread of Cr–F bond distances ranging from 1.78–1.80 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Cr4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Cr4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Cr4+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Cr4+ atom.
