Materials Data on AsS4N5F6 by Materials Project
N5S4AsF6 crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of four AsF6 clusters and four N5S4 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 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 N5S4 cluster, there are five inequivalent N+1.80+ sites. In the first N+1.80+ site, N+1.80+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.56 Å) and one longer (1.70 Å) N–S bond length. In the second N+1.80+ site, N+1.80+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.56 Å) and one longer (1.70 Å) N–S bond length. In the third N+1.80+ site, N+1.80+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.57 Å) and one longer (1.70 Å) N–S bond length. In the fourth N+1.80+ site, N+1.80+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.56 Å) and one longer (1.70 Å) N–S bond length. In the fifth N+1.80+ site, N+1.80+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.62 Å) and one longer (1.63 Å) N–S bond length. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted bent 120 degrees geometry to two N+1.80+ atoms. In the second S2- site, S2- is bonded in a trigonal non-coplanar geometry to three N+1.80+ atoms. In the third S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to three N+1.80+ atoms. In the fourth S2- site, S2- is bonded in a distorted bent 120 degrees geometry to two N+1.80+ atoms.
