Materials Data on Te7As2F12 by Materials Project

Abstract

(Te)7(AsF6)2 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of twenty-eight tellurium molecules and eight AsF6 clusters. In each AsF6 cluster, As1+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.77–1.79 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As1+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As1+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As1+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As1+ atom.
