Preparation and X‐Ray structural analysis of the remarkably stable Bis(triphenylmethyl)trisulfane‐2‐oxide R 2 S 3 O

Triphenylmethylthiol reacts with thionylchloride in the presence of amines to give [(C 6 H 5 ) 3 CS] 2 SO which crystallizes with one mole of CS 2 in the triclinic space group P 1 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 R 2 S 3 O molecules are of C 1 symmetry containing an almost planar CSSSC backbone with d ss = 212.7(1) and 211.4(1) pm, d cs = 188.0(2) and 188.2(2) pm, d so = 146.9(1) pm, α SSS = 83.8°, α SSO = 112.0° and 112.2°, τ CSSS = 160.7° and −172.3°.
