Materials Data on As(IF3)2 by Materials Project

Abstract

AsF6(I)2 crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of eight hydriodic acid molecules and four AsF6 clusters. In each AsF6 cluster, As2+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.73–1.80 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As2+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As2+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As2+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As2+ atom.
