    Description / Table of Contents: The Crystal Structure of 5-Oxo-1,3λ4,2,4-dithiazole, S2N2CO, and its Adducts with Lewis AcidsA simple synthesis of 5-oxo-1,3λ4,2,4-dithiadiazole (S2N2CO, 1) is reported. 1 crystallizes in the space group Pbca-D-2n15 and is a five-membered planar ring. Reactions of 1 in CH2Cl2 with the Lewis acids A yield the mono- and bisadducts S2N2CO · A and (S2N2CO)2 · A, where A = BF3 (2a), SO3 (2b), SbCl5 (2c), SbF2Cl3 (2d), SnCl4 (3a), and TiCl4 (3b). IR and Raman spectra are reported and possible structures of the adducts are discussed.
    Notes: Es wird eine einfache Synthese für 5-Oxo-1,3λ4,2,4-dithiadiazol (S2N2CO. 1) beschrieben. 1 kristallisiert in der Raumgruppe Pbca-D2n15 und ist ein fünfgliedriger planarer Ring. Reaktionen von 1 in CH2Cl2 mit den Lewis-Säuren A ergeben die Mono- und Bisaddukte S2N2CO · A und (S2N2CO)2 · A, wobei A = BF3 (2a), SO3 (2b), SbCl5 (2c), SbF2Cl3 (2d), SnCl4 (3a) und TiCl4 (3b) ist. IR- und Raman-Spektren werden mitgeteilt und mögliche Strukturen der Addukte diskutiert.
