Kristallstruktur und spektroskopische Charakterisierung von Hexamethyl- disilazan-Aluminiumtrichlorid [(H3C)3Si]2NH ∙ AlCl3 / Crystal Structure and Spectroscopic Characterisation of Hexamethyl- disilazane-trichloroalum inum [(H3C)3Si]2NH ∙ AlCl3

Abstract

Abstract By reaction of hexamethyldisilazane with aluminium trichloride in hexane hexamethyldisilazane-trichloroaluminum [(H3C)3Si]2NH • AlCl3 is formed. The adduct has been characterized by MS, IR, Raman, 1H, 13C, 27Al, 29Si NMR spectroscopy, and by a crystal structure determination (1425 independent reflections, R = 0.035). The space group is Pbca with a = 1312,6(5), b = 1182,9(5), c = 1964,7(5) pm; Z = 8. [(H3C)3Si]2NH • AlCl3 forms monomeric units which have point symme­try C1 and exhibit an Al − N bond length of 193,9(3) pm.
