Materials Data on As2S3 by Materials Project

As2S3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two As2S3 sheets oriented in the (0, 1, 0) direction. there are two inequivalent As3+ sites. In the first As3+ site, As3+ is bonded in a distorted trigonal non-coplanar geometry to three S2- atoms. There are a spread of As–S bond distances ranging from 2.28–2.31 Å. In the second As3+ site, As3+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are two shorter (2.29 Å) and one longer (2.30 Å) As–S bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in an L-shaped geometry to two As3+ atoms. In the second S2- site, S2- is bonded in a water-like geometry to two As3+ atoms. In the third S2- site, S2- is bonded in a water-like geometry to two As3+ atoms.

Materials Data on As2S3(NF6)2 by Materials Project

N2S3(AsF6)2 crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of eight AsF6 clusters and four N2S3 clusters. In each AsF6 cluster, As5+ 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 six 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 the third F1- site, F1- is bonded in a distorted single-bond geometry to one As5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In each N2S3 cluster, N4+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.55 Å) and one longer (1.61 Å) N–S bond length. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted water-like geometry to two equivalent N4+ atoms. In the second S2- site, S2- is bonded in a distorted single-bond geometry to one N4+ atom. In the third S2- site, S2- is bonded in a distorted single-bond geometry to one N4+ atom. The S–N bond length is 1.55 Å.
