    Description / Table of Contents: Crystal Structure of (NMe4)2[Re3Br11(H2O)] [Re3Br9(H2O)3](H2O)2.(NMe4)2[Re3Br11(H2O)] [Re3Br9(H2O)3](H2O)2 crystallizes from hydrobromic acid solution of Re3Br9 · 2 H2O and NMe4Br at 0 - 5°C. The crystal structure (monoclinic; P21/m (Nr. 11); a = 967.9(3); b = 1 529.7(4); c = 1 710.9(4) pm; β = 91.66(2)°; Z = 2; R = 0.113; Rw = 0.068) has been determined from four-circle diffractometer data. The structure contains two different cluster units of trivalent rhenium, isolated anionic [Re3Br11(H2O)]2- units and neutral cluster units that are connected through crystal water molecules to chains∞1{[Re3Br9(H2O)3](H2O)2}.
    Notes: (NMe4)2[Re3Br11(H2O)] [Re3Br9(H2O)3](H2O)2 kristallisiert aus einer bromwasserstoffsauren Lösung von Re3Br9 · 2 H2O und NMe4Br als dunkel-rotbraune Einkristalle bei 0 - 5°C aus. Die Kristallstruktur wurde aus Vierkreis-Diffraktometerdaten bestimmt: monoklin; P21/m (Nr. 11); a = 967,9(3); b = 1 529,7(4); c = 1 710,9(4) pm; β = 91,66(2)°; Z = 2; R = 0,113; Rw = 0,068. In der Struktur liegen zwei unterschiedliche Clustereinheiten vor: Eine anionische, isolierte Baueinheit, [Re3Br11(H2O)]2-, sowie eine neutrale über Kristallwasser zu Strängen gemäß ∞1{[Re3Br9(H2O)3](H2O)2} verknüpfte Einheit.
