Abstract

N2S3AsF6 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two AsF6 clusters and two N2S3 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 1.77–1.80 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted 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. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As2+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As2+ atom. In each N2S3 cluster, there are two inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.58 Å) and one longer (1.60 Å) N–S bond length. In the second N5+ site, N5+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.58 Å) and one longer (1.60 Å) N–S bond length. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a single-bond geometry to one N5+ atom. In the second S2- site, S2- is bonded in a distorted water-like geometry to two N5+ atoms. In the third S2- site, S2- is bonded in a distorted single-bond geometry to one N5+ atom.
