    Description / Table of Contents: Separation and Characterization of Chloro-aquo-hydroxo-oxo-osmates(IV)As a result of the acidic hydrolysis of hexachloroosmate(IV), OsCl62-, and/or the careful reduction of osmium tetroxide with iron(II) sulfate in hydrochloric acid products have been obtained which have been separated by column chromatography using diethylaminoethyl cellulose. On the basis of the analytically determined Os:Cl ratios, the ionic charges that could be deduced from the elution behaviour, and the absorption spectra the products have been characterized as the monomers OsCl5(H2O)-, cis-OsCl4(OH)(H2O)-, fac-OsCl3(OH)2(H2O)- and mer-OsCl3(OH)(H2O)2, the O-bridged dimers Cl5Os—O—OsCl54-, cis-(H2O)Cl4Os—O—OsCl4(H2O)2-and fac-(H2O)(OH)Cl3Os—O—OsCl3(OH)(H2O)2- and the hydrogen bridges forming OH-bridged dimers shown in “Inhaltsübersicht”.
    Notes: Die bei der sauren Hydrolyse von Hexachloroosmat(IV), OsCl62-, und/oder der vorsichtigen Reduktion von Osmiumtetroxid mit Eisen(II)-sulfat in salzsaurer Lösung entstehenden Reaktionsprodukte wurden säulenchromatographisch an Diethylaminoethylcellulose getrennt. Auf Grund der analytisch bestimmten Os:Cl-Verhältnisse, der aus dem Elutionsverhalten erhältlichen Ionenladungen und der Absorptionsspektren handelt es sich um die Monomeren OsCl5(H2O)-, cis-OsCl4(OH)(H2O)-, fac-OsCl3(OH)2(H2O)- und mer-OsCl3(OH)(H2O)2, die O-verbrückten Dimeren Cl5Os—O—OsCl54-, cis-(H2O)Cl4Os—O—OsCl4(H2O)2- und fac-(H2O)(OH) Cl3Os—O—OsCl3(OH)(H2O)2- sowie die Wasserstoffbrücken ausbildenden OH-verbrückten Dimeren .
