Materials Data on CsC2S2N(O2F3)2 by Materials Project

Abstract

(Cs(SO2)2)2N2(CF3)4 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of eight ammonia molecules; sixteen fluoroform molecules; and two Cs(SO2)2 sheets oriented in the (1, 0, 0) direction. In each Cs(SO2)2 sheet, Cs1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.13–3.36 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both S–O bond lengths are 1.45 Å. In the second S2+ site, S2+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both S–O bond lengths are 1.45 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 two equivalent Cs1+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one S2+ atom.
