Materials Data on SNF by Materials Project
NSF crystallizes in the tetragonal P-42_1c space group. The structure is zero-dimensional and consists of two NSF clusters. N3+ is bonded in a bent 120 degrees geometry to two equivalent S2- atoms. There is one shorter (1.55 Å) and one longer (1.67 Å) N–S bond length. S2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent N3+ and one F1- atom. The S–F bond length is 1.67 Å. F1- is bonded in a single-bond geometry to one S2- atom.
