Notes:
S12 · CS2 kristallisiert in der trigonalen Raumgruppe R&3macr;m-D3d5 mit den hexagonalen Gitterkonstanten a = 1066,8(3), c = 1155,1(4) pm, Z = 3, dber. = 2,04 g · cm-3. Die S12-Moleküle besetzen Lagen der Symmetrie D3d mit dem Kernabstand (d) 205,4(1) pm, den Valenzwinkeln (α) 105,80(5) und 106,65(6)º und dem Torsionswinkel (τ) 87,20(7)º. Das CS2-Molekül ist nur sehr locker gebunden.S12 kristallisiert in der orthorhombischen Raumgruppe Pnnm - D2h12 mit den Gitterkonstanten a = 472,5(2), b = 910,4(3), c = 1453,2(3) pm, Z = 2, dber. = 2,045 g · cm-3. Die Moleküle besetzen Lagen der Symmetrie C2h, die mittleren Molekülparameter sind: dss = 205,2 pm, α = 106,6º, τ = 88,0º.
