 Title    Vergleichende Röntgenstrukturanalysen von Naphthothiadiazinen und isovalenzelektronischen Naphthotriazinen-I-nstitut für B iochem ie, A bt. Strukturforschung I, D-8033 Martinsried  
 Abstract    Röntgenstrukturanalysen von Acenaphthyleno[5,6-cd][l,2,6]-thiadiazin, 2-Methyl-2 H-acenaphthyleno[5,6-de]-l,2,3-triazin und Naphtho[l,8-de]thiadiazin Comparison of Naphthothiadiazines and Isoelectronic Naphthotriazines by X-Ray Structural Analysis X-Ray Structural Analyses of A cenaphthyleno[5,6-cd][l,2,6]thiadiazine, 2-M ethyl-2H -acenaphthyleno[5,6-de]-l,2,3-triazine and N ap h th o [l,8-de]thiadiazine We have performed an X-ray structural analysis of the sulphur diimide 1 and the isoelectronic triazine 2. In addition we found two crystal m odifications o f the sulphur diimide 3, which is an analogue o f the previously characterized 4, but the m odification suitable for X-ray analysis (tetra­ gonal, ß) was disordered. From the bond lengths o f 1 and 2 results, that in both cases there is only
