    Description / Table of Contents: Synthese, Molekül- und Kristallstruktur eines zweiten Hydrates des Rheniumtrichlorids: [Re3Cl9(H2O)3] · 10 H2ODas Dekahydrat von [Re3Cl9(H2O)3] erhält man aus der wäßrigen Lösung von ReCl3 bei Temperaturen von 0 bis -5°C. Die Kristallstruktur (orthorhombisch, Pnma, Z = 4; a = 1 125,16(3), b = 1 630,30(5), c = 1 378,84(5) pm) wurde aus Einkristall-Diffraktometer-Daten bestimmt. Die Moleküle [Re3Cl9(H2O)3] werden in Richtung [0 1 0] gestapelt und durch Kristallwasser voneinander getrennt. Gemeinsam mit dem „Koordinationswasser“ in den Molekülen bilden sie ein System starker Wasserstoffbrücken-Bindungen, wenn dies aus den kurzen Abständen d (O—O) = 277 pm alleine geschlossen werden darf.
    Notes: The decahydrate of [Re3Cl9(H2O)3] is obtained from aqueous solutions of ReCl3 at zero to -5°C. The crystal structure (orthorhombic, Pnma, Z = 4; a = 1125.16(3), b = 1 630.30(5), c = 1 378.84(5) pm) has been determined from single-crystal X-ray diffractometer data. The [Re3Cl9(H2O)3] molecules are stacked in the [0 1 0] direction and the rows of such molecules are separated by the crystal water molecules. Together with the water ligands, these form a rather strong hydrogen bonding system judging from O—O distances (d = 277 pm) alone.
