Materials Data on AsS4N4F5 by Materials Project
(NS)4AsF5 crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two 1,3,5,7,2,4,6,8-tetrathiatetrazocane molecules and two AsF5 clusters. In each AsF5 cluster, As5+ is bonded in a square pyramidal geometry to five F1- atoms. There is one shorter (1.76 Å) and four longer (1.78 Å) As–F bond length. 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.
