Abstract

(Te)3(AsF6)2AsF3 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of twenty-four tellurium molecules, eight trifluoroarsine molecules, and sixteen 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 1.76–1.79 Å. There are six 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. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As1- atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As1- atom.
