Darstellung und Struktur des N-Thiobis-N′ -(phenylsulfonyl)schwefeldiimids / Synthesis and Structure of N-Thiobis-N′-(phenylsulfonyl)sulfurdiimide

The reaction of S 4 N 4 with PhSO 2 NCl 2 proceeds with formation of (PhSO 2 NSN) 2 S 2. The main product 2 was characterized by an X-ray structure determination. [P2 1 /c, a = 996.8(2), b = 1733.0(2), c = 1131.2(1) pm, β = 114.69(1)°, Z = 4, R = 0.044 for 1911 reflections.] 2 contains a sulfur-nitrogen chain with a planar central N 4 S 3 -Unit. The substituents at the NSN-groups are in cis-trans positions. 2 reacts with AgAsF 6 to yield the 1:1 complex 3; attempts to recrystallise this from CH 2 Cl 2 led to 2 · CH2Cl 2 , which was also subjected to a crystal structure determination [P1̄, a = 554.4(2), b = 1313.5(4), c = 1541.3(4) pm, α = 111.05(2), β = 94.61(2), γ = 92.24(2)°. Z = 2. R = 0.088 for 1728 reflections]. Minor differences between the two forms of 2 are observed.
