Abstract The molecular structure of Ph 3 CSSC(S)SCPh 3 · CS 2 has been determined by X‐ray structural analysis. The substance crystallizes in the triclinic crystal system [a = 884.9(2) pm, b = 1 039.5(2) pm, c = 2 064.6(3) pm, α = 75.86(1)°, β = 79.83(2)°, γ = 77.31(5)°, Z = 2, space group P 1 ]. The CS 3 group is planar; the SS‐bond (201.4 pm) forms an angle of 5.7° with the CS 3 plane. The torsional angle CSSC equals 96.3°. (Ph 3 C) 2 CS 4 was obtained by reaction of TosNSCl 2 (Tos = p‐MeC 6 H 4 SO 2 ) with Ph 3 CSH in CS 2 in the presence of triethylamine. The reaction mechanism is discussed.
