Synthese und Kristallstruktur eines zweikernigen Ylid‐Komplexes mit Metall‐Metall‐Bindung zwischen Goldatomen der Oxidationsstufe + II1)

Abstract: The [diethylphosphoniumbis(methylido)]gold(I) dimer 4 reacts with one equivalent of chlorine, bromine, or iodine to give a series of compounds 5a-e, for which a bicyclic structure with a remarkably short transannular gold-gold hond (229.7 pm) is demonstrated hy means of analytical and s p i r a l data as wcll as by an X-ray analysis of 5a. The two metals of formal oxidation state + I1 are separated by a very short distance.Im Verlauf ausgedehnter Arbeiten uber Ylid-Komplexe des Golds *. waren durch partielle b… Show more

“…Gold complexes with P –C– P 24 and S –C– S 25 bridges are also reported as well as silver and copper compounds with the N –C– N bridge 26. Special gold complexes with the C –P– C bridge were reported very early by the group of Schmidbaur involving the anionic phosphorus ylide [CH 2 P(Et) 2 CH 2 ] – 27 however, no related silver compounds are known. The length of the M ··· M contact depends on nature of the X –Y– Z bridge.…”

“…[9] Alternativ zur Disproportionierung wird Gold(II) durch Dimerisierung unter Bildung einer Au 2 4+ -Einheit oder durch Oligomerisierung zu Clusterverbindungen stabilisiert.

[5] Dieser Pfad wird besonders durch die Au-Au-Bindung potentiell verbrückende Liganden, wie SO 4 2À (Au-Au2 .490 ), [CH 2 PR 2 CH 2 ] À oder [S 2 CNR 2 ] À (2.550-2.694 ), bevorzugt.…”

“…Um Zersetzung zu verhindern, wurden alle Xenonkomplexe aus HF/SbF 5 -Mischungen unter Xenonatmosphäre bei tiefen Te mperaturen präpariert. [19,21,22] [6,10,11,13,14] ma 2). [21,22] Allen diesen Gold(II)-Komplexen sind die eher harten Donorliganden ohne Anzeichen für" nicht-unschuldiges" Redoxverhalten gemein (Schema 2).…”
