    Description / Table of Contents: Investigation of the Structure of Alkoxoarsenic(V) NitridesUsing electron impact mass spectrometry, it could be proved that NAs(OCH3)2 and NAs(OC2H5)2 form trimeric, tetrameric, pentameric and hexameric units. The trimeric molecule is the main constituent. The cyclic compounds with As—N double bonds are like the phosphazenes. Combined 1H-NMR, Raman and IR data indicate a plane ring for the trimeric. Most of the fragmentations in the ion source of the mass spectrometer are elucidated.
    Notes: Massenspektroskopisch kann nachgewiesen werden, daß NAs(OCH3)2 und NAs(OC2H5)2 Gemische aus trimeren, tetrameren, pentameren und hexameren Moleküleinheiten sind, wobei das Trimere überwiegt. In den Ringen treten As—N-Doppelbindungsanteile auf. Aus 1H-NMR-, RAMAN- und IR-Spektren folgt, daß der Ring in der trimeren Verbindung eben ist. Die Fragmentierungen in der Ionenquelle des Massenspektrometers werden weitestgehend aufgeklärt.
