Materials Data on As(IF2)3 by Materials Project

Abstract

As(IF3)2I crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two hydriodic acid molecules and two As(IF3)2 clusters. In each As(IF3)2 cluster, As3+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.76–1.81 Å. There are two inequivalent I1+ sites. In the first I1+ site, I1+ is bonded in a single-bond geometry to one F1- atom. The I–F bond length is 2.66 Å. In the second I1+ site, I1+ is bonded in a single-bond geometry to one F1- atom. The I–F bond length is 2.80 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As3+ and one I1+ atom. In the fifth F1- site, F1- is bonded in a distorted single-bond geometry to one As3+ and one I1+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As3+ atom.
