    Description / Table of Contents: Darstellung und Röntgenstrukturanalyse des bemerkenswert stabilen Bis(triphenylmethyl)trisulfan-2-oxids R2S3O [1]Triphenylmethylthiol reagiert in Gegenwart von Aminen mit Thionylchlorid zu [(C6H5)3CS]2SO, das als Solvat mit 1 Mol CS2 kristallisiert: triklin, Raumgruppe P1 mit 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)α, ρ = 1,354 g cm-3 bei -80°C. Das Trisulfanoxidmolekül R2S3O ist von C1-Symmetrie und weist ein fast planares Gerüst CSSSC auf mit den im Abstract angegebenen geometrischen Parametern.
    Notes: 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°.

    Description / Table of Contents: Kristall- und Molekülstruktur von Dicyanotetrasulfan S4(CN)2S4(CN)2 kristallisiert in der monoklinen Raumgruppe P21/c mit den im Abstract angegebenen Parametern. Die Moleküle besetzen allgemeine Lagen, sind aber ungefähr von C2-Symmetrie. Die Konformation ist all-trans mit den Torsionswinkeln CSSS = 74,6° und 81,7° sowie SSSS = 84,8°. Die mittlere SS-Bindung (201,7 pm) ist viel kürzer als die äußeren (Mittelwert 206,8 pm). Die intermolekularen Wechselwirkungen sind vom van-der-Waals-Typ.
    Notes: S4(CN)2 crystallizes in the monoclinic space group P21/c with a = 885.7 pm, b = 794.2 pm, c = 1032.6 pm, β = 109.0° (at 173 K). The molecules occupy general sites but are of approximate C2 symmetry. The conformation of the molecules is all-trans with torsional angles CSSS = 74.6° and 81.7° and SSSS = 84.8°. The central SS bond (201.7 pm) is much shorter than the terminal SS bonds (av. 206.8 pm). There are no stronger than van-der-Waals type intermolecular interactions.
