Materials Data on AsS2NF6 by Materials Project

Abstract

NS2AsF6 crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two AsF6 clusters and two NS2 clusters. In each AsF6 cluster, As5+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.77 Å) and four longer (1.78 Å) As–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In each NS2 cluster, N5+ is bonded in a linear geometry to two equivalent S2- atoms. Both N–S bond lengths are 1.49 Å. S2- is bonded in a distorted single-bond geometry to one N5+ atom.
