    Description / Table of Contents: Ein Derivat der Perthiokohlensäure H2CS4: Röntgenstrukturanalyse von Bis(triphenylmethyl)perthiocarbonat (Ph3C)2CS4Die Molekülstruktur von Ph3CSSC(S)SCPh3 · CS2 wurde durch eine Röntgenstrukturanalyse bestimmt. Die Substanz kristallisiert im triklinen Kristallsystem [a = 884,9(2) pm, b = 1 039,5(2) pm, c = 2 064,6(3) pm, α = 75,86(1)°, γ = 79,83(2)°, γ = 77,31(5)°, Z = 2, Raumgruppe P1]. Die CS3-Gruppe ist planar; die S—S-Bindung (201,4 pm) bildet mit der CS3-Ebene einen Winkel von 5,7°. Der CSSC-Torsionswinkel beträgt 96,3°. (Ph3C)2CS4 wurde durch Umsetzung von TosNSCl2 (Tos = p-MeC6H4SO2) mit Ph3CSH in CS2 in Gegenwart von Triethylamin erhalten. Der Reaktionsmechanismus wird diskutiert.
    Notes: The molecular structure of Ph3CSSC(S)SCPh3 · CS2 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 P1]. The CS3 group is planar; the S—S-bond (201.4 pm) forms an angle of 5.7° with the CS3 plane. The torsional angle CSSC equals 96.3°. (Ph3C)2CS4 was obtained by reaction of TosNSCl2 (Tos = p-MeC6H4SO2) with Ph3CSH in CS2 in the presence of triethylamine. The reaction mechanism is discussed.
