Materials Data on CsS2N(O2F)2 by Materials Project
(CsS2(O2F)2)2N2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four ammonia molecules and one CsS2(O2F)2 framework. In the CsS2(O2F)2 framework, Cs1+ is bonded in a 8-coordinate geometry to six O2- and two F1- atoms. There are a spread of Cs–O bond distances ranging from 3.20–3.32 Å. Both Cs–F bond lengths are 3.49 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to two O2- and one F1- atom. Both S–O bond lengths are 1.44 Å. The S–F bond length is 1.64 Å. In the second S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to two O2- and one F1- atom. There is one shorter (1.43 Å) and one longer (1.44 Å) S–O bond length. The S–F bond length is 1.62 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to two equivalent Cs1+ and one S2+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Cs1+ and one S2+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Cs1+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to two equivalent Cs1+ and one S2+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one S2+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one S2+ atom.
