Materials Data on AsH2SNF10 by Materials Project
NH2SF4AsF6 is Modderite-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two AsF6 clusters and two NH2SF4 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 1.76–1.79 Å. There are three 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 single-bond geometry to one As5+ atom. In each NH2SF4 cluster, N5+ is bonded in a trigonal planar geometry to two H1+ and one S2- atom. Both N–H bond lengths are 1.03 Å. The N–S bond length is 1.55 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. S2- is bonded in a trigonal bipyramidal geometry to one N5+ and four F1- atoms. There is two shorter (1.55 Å) and two longer (1.59 Å) S–F bond length. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one S2- atom. In the second F1- site, F1- is bonded in a single-bond geometry to one S2- atom. In the third F1- site, F1- is bonded in a single-bond geometry to one S2- atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one S2- atom.
