Preparation and X‐Ray structural analysis of the remarkably stable Bis(triphenylmethyl)trisulfane‐2‐oxide R2S3O

This is the authors' abstract. We don't add key points for this paper.

Triphenylmethylthiol reacts with thionylchloride in the presence of amines to give [(C6H5)3CS]2SO which crystallizes with one mole of CS2 in the triclinic space group P1 with a = 1 193.4(4), b = 1 266.8(5), c = 1 421.6(7) pm, α = 63.79(2)°, β = 65.25(2)°, γ = 63.18(2)°, π = 1.354 g cm−3 at −80°C. The R2S3O molecules are of C1 symmetry containing an almost planar CSSSC backbone with dss = 212.7(1) and 211.4(1) pm, dcs = 188.0(2) and 188.2(2) pm, dso = 146.9(1) pm, αSSS = 83.8°, αSSO = 112.0° and 112.2°, τCSSS = 160.7° and −172.3°.
