    Description / Table of Contents: S4N4 and its Derivatives: [Cu(CH3CN)CL2]2S2N2, a Transition Metal Complex with the S2N2 LigandS4N4 reacts with CuCl2 · 2H2O in acetonitrile to give among other products the polymer copper(II) complex [Cu(CH3CN)Cl2]2S2N2, This complex crystallizes in the space group P21/c with a = 9.635(4), b = 7.270(4), c = 10.009(6) Å, β = 93.16(6)°, and Z = 2. An X-ray structure analysis (R = 0,065) shows the crystal to.contain parallel chains with copper atoms bridged by Cl and S2N2 bridges. The coordination of the Cu atom is square pyramidal. The S2N2 ring is planar. The SN bond distances are 1.633 and 1.641 Å.
    Notes: Bei der Umsetzung von S4N4 mit CuCl2 · 2H2O in Acetonitril entsteht neben anderen Produkten der polymer gebaute Kupfer(II)-Komplex [Cu(CH3CN)Cl2]2S2N2. Er kristallisiert in der Raumgruppe P21/c mit a = 9,635(4), b = 7,270(4), c = 10,009(6) Å, β = 93,16(6)° und Z = 2. Eine Röntgenetrukturanalyse (R = 0,065) ergibt, daß im Kristall parallele Ketten vorliegen, wobei die Kupferatome alternierend durch zwei Cl-Brücken und durch eine S2N2-Gruppe verknüpft sind. Die Koordination des Kupfers ist quadratisch pyramidal. Der S2N2-Ring ist eben gebaut. Die SN-Bindungsabstände betragen 1,633 und 1,641 Å.
