Description / Table of Contents:
Complex Cation [(AnH)3(H2O)2]3+ in Trianilinium-tri-μ-chloro-nonachloro-trirhenate(III)-dihydrate, (AnH)3[Re3(μ-Cl3)Cl9] · 2 H2ODark red single crystals of trianilinium-tri-μ-chloro-nonachloro-trirhenate(III)-dihydrate grow from hydrochloric acid solutions of “ReCl3 · 2 H2O” and anilinium hydrochloride. An important feature of the crystal structure (monoclinic, P21/a, Z = 4, a = 1595.98(12), b = 1594.53(11), c = 1319.65 (9) pm, β = 100.20(1)°, Vm = 497.68(1) cm3 mol-1) are complex cations of the composition [(AnH)3(H2O)2]3+. The N—O- and O—O-distances in the hydrogen bonded cation [(AnH)3(H2O)2]3+ are 281 to 289 pm and 287, respectively. The cationic layers build up corrugated layers parallel (010) and leave two channels in the [010] direction per unit cell into which the anionic clusters, [Re3Cl12]3-, are embedded.
Notes:
Dunkelrote Einkristalle von Trianilinium-tri-μ-chloro-nonachloro-tri-rhenat(III)-dihydrat erhält man aus salzsauren Lösungen von „ReCl3 · 2 H2O“ und Aniliniumhydrochlorid. In der Kristallstruktur (monoklin, P21/a, Z = 4, a = 1595,98(12), b = 1594,53(11), c = 1319,65(9) pm, β = 100,20(1)°, Vm = 497,68(1) cm3 mol-1) sind drei Aniliniumkationen und zwei Wassermoleküle über Wasserstoff-Brückenbindungen zu einem komplexen Kation [(AnH)3(H2O)2]3+ verbunden. Innerhalb dieser Baugruppe findet man N—O-Bindungsabstände zwischen 281 und 289 pm sowie einen O—O-Abstand von 287 pm. Die komplexen Kationen [(AnH)3(H2O)2]3+ sind parallel (010) zu gewellten Schichten angeordnet, die je Elementarzelle zwei Kanäle in Richtung [010] freilassen, in die die Anionen [Re3Cl12]3- eingebettet sind.
