    Description / Table of Contents: The preparation of tris-(trimethylsilyl) amine and its chemical and physical properties are described. The RAMAN- and infrared-spectra of this compound and those of methyltrimethylsilyl-amine, dimethyl-trimethylsilyl-amine, bis-(trimethylsilyl)-amine, and methyl-bis-(trimethylsilyl)-amine are reported and the frequencies assigned. It is assumed, that the bond forces of the N—Si-bonds are higher then 1.0; presumably the group NSi3 is not completely planar.
    Notes: Aus dem Natriumsalz des Hexamethyldisilazans und Trimethylchlorsilan wird Tris-(trimethylsilyl)-amin dargestellt - Fp. 70-71°, Kp.12mm 76°, d20 = 0,8635, nD20 = 1,4545, Dipolmoment 0,51 D -, eine weiße, gegenüber Wasser und auch ziemlich starker Natronlauge widerstandsfähige Substanz. Von dieser Verbindung sowie von Methyl-trimethylsily-amin, Dimethyl-trimethylsilyl-amin, Hexa- und Heptamethyl-disilazan wurden die RAMAN- und Infrarot-Spektren aufgenommen und ausgedeutet. Aus dieser Untersuchung wird geschlossen, daß das freie Elektronenpaar am Stickstoff teilweise als π-Elektronen die SiN-Bindungen verstärkt. Vollständige Planartät liegt wahrscheinlich nicht vor.
