 Title    Untersuchungen über die Wechselwirkung von Aromaten mit Antimontrichlorid, IV* Elektronenspektroskopische Untersuchung zur Frage der Farbigkeit der Molekülverbindung ArH * 2 SbCl3 Investigations about the Interaction of Aromatic Compounds with Antimonytrichloride, IV* Elektronspectroscopical Investigation about the Colour of the Aromatics * 2 SbCl3 Complexes  
 Abstract    Contrary to the published results it is shown the colour of the solid molecular complexes arene • 2 SbCl3 is due to impurities in these systems. These impurities are mainly the radical ions of the aromatic compounds. If the formation of these radical ions is avoided the complexes in the solid state are colourless or slightly yellow-coloured.

 Title    Cyclische Diazastannylene, II 1 Intermolekulare Lewis-Säure-Base-Addukte bei 1.3.2.4A 2 -Diazasilastannetidinen Cyclic Diazastannylenes, II 1 Intermolecular Lewis-Acid-Base Adducts of 1, 3,2,4A 2 -Diazasilastannetidines  
 Abstract    -diazasilastannetidines can be prepared as mono-mers (organyl = <erf-butyl) or dimers (organyl = isopropyl) in nonpolar solvents, depending on the organic nitrogen substituent. The formation of the dimer, which is due to an intermolecular Lewis-acid-base interaction of Sn(II) with nitrogen, can be initiated by solidification. When the tertf-butyl compound is cooled below 0 °C two crystalline modi-fications are found: a monoclinic phase (C 2/c; a= 10.655(5); b = 24.75(1); c = 17.334(9) Ä; ß = 106.9(1)°) and a triclinic phase (P I; a = 10.68(1); b = 13.51(1); c = 12.36(1) A; a = 96.2(1); ß = 102.6(1); y = 118.4(1)°). The crystal structures turn out to be built of dimeric and monomeric units in the first case and presumably only dimeric species in the second case. The isopropyl derivative crystallizes in the space group P 2i/b (a = 10.77(1); b= 12.14(2); c = 11.15(2) A; ß = 120.2(2)°) with only dimeric units being present, as in the liquid. Interrelationships between the three structures are discussed.
