    Description / Table of Contents: mehrkernige Technetium-Cluster. I. Synthese, Kristall- und Molekularstruktur der Bromide achtkerniger prismatischer und sechskerniger oktaedrischer Cluster des TechnetiumsE werden die Synthese, Kristall- und Molekularstruktur erster Vertreter mehrkerniger Technetium-Cluster er Zusammensetzung: [Tc8Br4μ—Br8]Br. 2 H2O; [H(H2O)2][Tc8Br4μ—Br8]Br; [H(H2O)2]2[Tc8Br4μ—Br8]Br2; [H3O(H2O)3]2[Tc6Br6μ3—Br5]; [(C4H9)4N]2[Tc6Br6μ3—Br5]; [H3O(H2O)3]2[Tc6Br6μ3—Br5]. 4 H2O beschrieben. Diese Verbindungen unterscheiden sich in ihrem Bau wesentlich von bekannten Clustern anderer d-Elemente. Die Kristall- und Molekularstruktur von Hexabromotechnetiumsäure, (H3O)2TcBr6, ist untersucht worden.
    Notes: The synthesis, crystal and molecular structure of the first representatives of polynuclear technetium clusters are described. The composition of these clusters is: [Tc8Br4μ—Br8]Br. 2H2O; [H(H2O)2][Tc8Br4μ—Br8]Br; [H(H2O)2]2[Tc8Br4μ—Br8]Br2; [H3O(H2O)3]2[Tc6Br6μ3—Br5]; [(C4H9)4N]2[Tc6Br6μ3—Br5]; [H3O3]2[Tc6Br6μ3—Br5]. 4 H2O. It is shown that these clusters strongly differ in their structure from the known clusters of other d-elements. The crystal and molecular structure of hexabromotechetium acid (H3O)2TcBr6 is studied too.
