N2Se2S(AsF6)2 crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of eight AsF6 clusters and four N2Se2S 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 N2Se2S cluster, there are two inequivalent N4+ sites. In the first N4+ site, N4+ is bonded in a bent 120 degrees geometry to one Se2- and one S2- atom. The N–Se bond length is 1.74 Å. The N–S bond length is 1.59 Å. In the second N4+ site, N4+ is bonded in a bent 120 degrees geometry to one Se2- and one S2- atom. The N–Se bond length is 1.74 Å. The N–S bond length is 1.59 Å. Se2- is bonded in a 1-coordinate geometry to one N4+ atom. S2- is bonded in a distorted water-like geometry to two N4+ atoms.
