Materials Data on SINOF2 by Materials Project
NS(O)F2I is Iron carbide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight hydriodic acid molecules and eight NS(O)F2 clusters. In four of the NS(O)F2 clusters, N1+ is bonded in a single-bond geometry to one S2- atom. The N–S bond length is 1.50 Å. S2- is bonded in a tetrahedral geometry to one N1+, one O2-, and two F1- atoms. The S–O bond length is 1.42 Å. There is one shorter (1.59 Å) and one longer (1.60 Å) S–F bond length. O2- is bonded in a single-bond geometry to one S2- atom. There are two 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 four of the NS(O)F2 clusters, N1+ is bonded in a single-bond geometry to one S2- atom. The N–S bond length is 1.50 Å. S2- is bonded in a tetrahedral geometry to one N1+, one O2-, and two F1- atoms. The S–O bond length is 1.42 Å. There is one shorter (1.58 Å) and one longer (1.59 Å) S–F bond length. O2- is bonded in a single-bond geometry to one S2- atom. There are two 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.
