    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.

    Description / Table of Contents: Darstellung spirocyclischer organischer Polysulfane des Typs C6H10Sn und Röntgenstrukturanalyse von C6H10S11Durch Reaktion von (C5H5)2Ti(μ-S2)2C6H10 3 mit S2Cl2 wurde 7,8,9,10,11,12-Hexathiaspiro[5,6]dodecan 4 hergestellt (Ausbeute 51%), das durch UV-, IR-, Raman-, Massen- und NMR-Spektren (1H, 13C) charakterisiert wurde. Die NMR-Spektren zeigen, daß der siebengliedrige CS6-Ring in Lösung Pseudorotation erleidet. Mit S7Cl2 reagiert der Komplex 3 zu 7,8,9,10,11,12,13,14,15,16,17-Undecathiaspiro-[5.11]heptadecan 5 (Ausbeute 23%). Die gelben, monoklinen Kristalle von 5 bestehen aus spirocyclischen C6H10S11-Molekülen, deren C6-Ring Sesselkonformation aufweist, während der CS11-Ring eine dem cyclo-Dodecaschwefel S12 entsprechende Konformation besitzt. Alle Glieder der homologen Reihe C6H10Sm (m = 5-14) wurden mittels HPLC charakterisiert.
    Notes: By reaction of (C5H5)2Ti(μ-S2)2C6H10 3 with S2Cl2 7,8,9,10,11,12-hexathiaspiro-[5.6]dodecane 4 is prepared (yield 51%) and characterized by UV, IR, Raman, mass, and NMR spectra (1H, 13C). The seven-membered CS6 ring undergoes pseudorotation in solution. With S7Cl2 the complex 3 yields 7,8,9,10,11,12,13,14,15,16,17-undecathiaspiro[5.11]heptadecane 5 (yield 23%). The yellow, monoclinic crystals of 5 consist of spirocyclic C6H10S11 molecules with the C6 ring in a chair-conformation while the CS11 ring is of the same conformation as cyclododecasulfur S12. UV, IR, Raman, mass and NMR-spectra of 5 are reported. A mixture of dichlorosulfanes SnCl2 (n = 1 -8) reacts with 3 to give the homologous series C6H10Sm which was characterized by reversed-phase HPLC for m = 5 - 14.
