Materials Data on CsC4S4N8O2F by Materials Project

Abstract

CsC2N4S2F(CN2)2(SO)2 crystallizes in the orthorhombic Ibam space group. The structure is two-dimensional and consists of eight formamidine molecules; eight sulfur monoxide molecules; and two CsC2N4S2F sheets oriented in the (0, 0, 1) direction. In each CsC2N4S2F sheet, Cs1+ is bonded in a 8-coordinate geometry to four equivalent N+0.50- atoms. All Cs–N bond lengths are 3.37 Å. C4+ is bonded in a trigonal planar geometry to two equivalent N+0.50- and one F1- atom. Both C–N bond lengths are 1.30 Å. The C–F bond length is 1.65 Å. N+0.50- is bonded in a 1-coordinate geometry to one Cs1+, one C4+, and one S2- atom. The N–S bond length is 1.80 Å. S2- is bonded in a distorted L-shaped geometry to two equivalent N+0.50- atoms. F1- is bonded in a linear geometry to two equivalent C4+ atoms.
