 Title    Aluminiumbromid-Pyridiniumbromid-Verbindung: Kristallstruktur Kristallstrukturbestimmung von [Tris(pyridinium)bromid]bis(tetrabromoaluminat(III)) Crystal Structure Determination of [Tris(pyridinium)bromide]bis(tetrabromoaluminate(III))  
 Abstract    The compound [(PyH) 3 Br][AlBr 4 ] 2 is formed by melting stoichiometric amounts of AlBr/PyHBr in a ratio of 2:3. It crystallizes in the orthorhombic space group Pbca with lattice constants a = 1365.5(2), b = 1616.0(2), c = 2783.7(3) pm, Z = 8, D c = 2.21 g/cm 3 . The structure was solved from 2810 diffractometer measured intensities (Cu —K" radiation) and refined to /?".(F) = 0.071. The cation shows three pyridinium ions attached via N — H — Br hydrogen bonds to a central bromide ion. The N-Br distances are 321(1), 321(2) and 332(2) pm.

 Title    Die Phasendiagramme der Systeme aus Dibromdimethylsilan und 2-, 3-oder 4-Methylpyridin The Phase Diagrams o f Systems Containing Dibromodimethylsilane and 2-, 3-or 4-M ethylpyridine  
 Abstract    By analyzing the DSC heating curves and the resulting phase diagrams o f the systems o f dibrom odimethylsilane and 2-, 3-or 4-methylpyridine the existence o f the congruently melting addition com pounds ((C H 3)2SiBr2)2-(3-methylpyridine) and (C H 3)2SiBr2 (4-methylpyridine)2, and the incongruently melting addition com pounds ((CH 3)2SiBr2)2 (2-methylpyridine) and ((C H 3)2SiBr2)2-(4-methylpyridine) could be proved.
