    Description / Table of Contents: μd,h-μ-Carboxilato-e-μ-methoxo-f-μ-oxo-bis[trichloroantimony(V)]. Preparation and SpectraThe preparation of the unknown d,h-μ-carboxilato-e-μ-methoxo-f-μ-oxo-bis[trichloroantimony(V)] compounds is described (CF3COO ≙ 2, CH3CH2COO ≙ 4). The vibrational spectra of 2 and 4 were assigned and compared with those of the corresponding hydroxo compounds 1 and 3. The mass spectra of 1 - 4 are measured and the fragmentation pathes are proposed. The formulae of some fragments of 1 with m/e values greater than the molecular weight were determined by high resolution.
    Notes: Aus der Klasse der bisher nicht bekannten d,h-μ-Carboxilato-μ-methoxo-f-μ-oxo-bis[trichloroantimon(V)]-Verbindungen wird die Darstellung der Trifluoracetato- 2 und Propionato-Verbindung 4 beschrieben. Die Schwingungsspektren von 2 und 4 werden zugeordnet und denen der entsprechenden Hydroxoverbindungen 1 und 3 gegenübergestellt. Die Massenspektren von 1 - 4 wurden aufgenommen und für die Zerfallswege wird ein Vorschlag gemacht. Für einige Bruchstücke von 1, deren m/e-Werte größer als die Molmasse von 1 sind, wurde durch Hochauflösung die Zusammensetzung ermittelt.

    Description / Table of Contents: Structure and Mass Spectra of the Series Sb(0Et)3 - SbCl3The crystal and molecular structures of ClSb(OEt)2, (II) and Cl2SbOEt (III) are determined by X-ray analysis. Both compounds crystallizes in the monoclinic space group P21/c. There are two dimensional planar layers in which the antimony is coordinated distorted octahedral. The mass spectra of the series Sb(OEt)3-SbCl3 (I-IV) are determined at 20 and 70 eV and the fragmentation processes are discussed.
    Notes: Die Kristall- und Molekülstrukturen des ClSb(OEt)2 (II) und des Cl2SbOEt (III) wurden röntgenographisch ermittelt. Beide kristallisieren monoklin in der Raumgruppe P21/c. Die Strukturen werden aus zweidimensionalen planaren Schichten aufgebaut, in denen die Sb-Atome verzerrt oktaedrisch koordiniert sind. Die Massenspektren der Reihe Sb(OEt)3-SbCl3 (I-IV) wurden bei 20 und 70 eV aufgenommen und die Fragmentierungsprozesse diskutiert.
