Au55[P(C6H5)3]12CI6 — ein Goldcluster ungewöhnlicher Größe
Abstract
Die Reduktion von C 6 H 5)3 PAuCl mit B 2 H 6 in Benzol ergibt Au 9,2[P(C 6 H 5)3]2 Cl, das mittels Molmassebestimmungen als Au 55[P(C 6 H 5)3]12 Cl 6 charakterisiert wurde. Ein einfaches Modell, beruhend auf einer Anordnung dichtest gepackter Goldatome, führt zu einem Goldcluster, dessen Aufbau mit der ungewöhnlichen chemischen Zusammensetzung in guter Übereinstimmung ist. Das Mößbauer‐Spektrum der Verbindung zeigt vier Sorten von Goldatomen: einen metallischen Anteil (Au 13‐Kern), durch P(C 6 H 5)3‐bzw. Cl‐Liganden Koordinierte Au‐Atome, sowie unkoordi‐niertes Oberflächengold. Mit Brom und lod läß sich der Komplex zu (C 6 H 5)3 PAuCl, (C 6 H 5)3 PAuBr(I) und metallischem Gold abbauen. Die Thermolyse bei 50°C führt quantitativ zu [(C 6 H 5)3 P]2 AuCl und Gold.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
