    Description / Table of Contents: Hydrolysis Products of Hexabromoosmate (IV), OsBr62-As a result of the acidic hydrolysis of hexabromoosmate(IV), OsBr62-, products were obtained which were separated by ion column chromatography using diethylaminoethylcellulose. On the basis of the analytically determined Os: Br ratios, the ionic charges that could be deduced from the elution behaviour, and the absorption spectra the products have been characterized as OsBr5(H2O)-, Br4(H2O)Os—;OH—;Os(H2O)Br4-, Br3(H2O)2Os—;OH—;Os(OH)(H2O)Br3, Br2(H2O)2(OH)Os—;OH—;Os(OH)(H2O)2Br2+ and OsBr(OH)m(H2O)5-m3-m (0 ≤ m ≤ 2). In the dimers intramolecular formation of hydrogen bonds is assumed.
    Notes: Die bei der sauren Hydrolyse von Hexabromoosmat(IV), OsBr62-, entstehenden Reaktionsprodukte wurden säulenchromatographisch an Diethylaminoethylcellulose getrennt. Auf Grund der analytisch bestimmten Os: Br-Verhältnisse, der aus dem Elutionsverhalten erhältlichen Ionenladungen und der Absorptionsspektren handelt es sich um OsBr5(H2O)-, Br4(H2O)Os—;OH—;Os(H2O)Br4-, Br3(H2O)2Os—;OH—;Os(OH)(H2O)Br3, Br2(H2O)2(OH)Os—;OH—;Os(OH)(H2O)2Br2+ sowie OsBr(OH)m(H2O)5-m3-m(O≤m≤2). In den Dimeren wird eine intramolekulare Verbrückung unter Ausbildung von Wasserstoffbrücken angenommen.
