Neue arsinidenverbrückte Mehrkern‐Clusterkomplexe des Ag und Au. Die Kristallstrukturen von [Ag14(AsPh)6Cl2(PR3)8], (PR3 = PEt3, PMenPr2, PnPr3), [M4(As4Ph4)2(PR3)4], (M = Ag, PR3 = PEt3, PnPr3; M = Au, PR3 = PnPr3), [A

Abstract: Bei der Reaktion von AgCl mit PhAs(SiMe3)2 bilden sich in Gegenwart der tertiären Phosphane PEt3, PMenPr2 und PnPr3 die Silbercluster der Zusammensetzung [Ag14(AsPh)6Cl2(PR3)8] (PR3 = PEt3 1, PMenPr2 2, PnPr3 3). Ferner konnten die Mehrkernkomplexe [Ag4(As4Ph4)2(PR3)4] (PR3 = PEt3 4, PMenPr2 5) isoliert werden. Bei analogen Umsetzungen von [PMe3AuCl] mit PhAs(SiMe3)2 und von PnPr3 bildet sich neben dem zu 4 und 5 isostrukturellen Goldkomplex [Au4(As4Ph4)2(PnPr3)4] 6 ein Goldcluster der Zusammensetzung [Au10(As… Show more

“…The Au 8 As 4 chain is built from two Au 3 As tetrahedra and two interpenetrating Au 2 As 2 tetrahedra, which share a common As1As2 edge from an As 2 n Pr 2 group. The appearance of ligands containing AsAs bonds, formed by redox side‐reactions, has also been observed for arsenide clusters of other coinage metals 2…”

“…A limited number of gold–arsenic complexes have been described in the literature, including compounds containing arsenic bridges (for example, [(Ph 3 PAu) 4 As]BF 4 ,1 [Au 4 (As 4 Ph 4 ) 2 (P n Pr 3 ) 4 ],2 and [Au 10 (AsPh) 4 (PhAsSiMe 3 ) 2 (P n Pr 3 ) 6 ]2) or terminal AsR 3 ligands (for example, [(Ph 3 As) x Au]BF 4 ( x =2, 4),3 [(Ph 3 AsAu) 3 O]BF 4 ,3 [Au(C 6 F 5 ){(SPh 2 ) 2 C(AuAsPh 3 ) 2 }]ClO 4 ,4 and [Au 4 Cl 2 {Ph 2 PCH 2 As(Ph)CH 2 PPh 2 } 2 ]X 2 (X=PF 6 , NO 3 )5), as well as [Au 16 (AsPh 3 ) 8 Cl 6 ], which contains a centered icosahedron of 13 gold atoms 6. In contrast, the rich chemistry of gold and gold–chalcogen clusters has been extensively studied 7–10.…”

“…However, their coordination chemistry has so far been only very little investigated [14a–d] and their use as linkers in supramolecular chemistry is rare. Moreover, coordination compounds of any polyarsenic linker and silver ions are extremely scarce [14a,c–e] . Accordingly, we were keen to expand this research area by studying the supramolecular chemistry of polyarsenic As n complexes and comparing it to that of their phosphorus analogues.…”

“…In der Literatur finden sich nur wenige Gold‐Arsen‐Komplexe: Beschrieben wurden beispielsweise Verbindungen mit Arsenbrücken – [(Ph 3 PAu) 4 As]BF 4 ,1 [Au 4 (As 4 Ph 4 ) 2 (P n Pr 3 ) 4 ]2 oder [Au 10 (AsPh) 4 (PhAsSiMe 3 ) 2 (P n Pr 3 ) 6 ]2 –, solche mit terminalen AsR 3 ‐Liganden – [(Ph 3 As) x Au]BF 4 ( x =2, 4),3 [{(Ph 3 As)Au 3 }O]BF 4 ,3 [Au(C 6 F 5 ){(SPh 2 ) 2 C(AuAsPh 3 ) 2 }]ClO 4 4 oder [Au 4 Cl 2 {Ph 2 PCH 2 As(Ph)CH 2 PPh 2 } 2 ]X 2 (X=PF 6 , NO 3 )5 – sowie [Au 16 (AsPh 3 ) 8 Cl 6 ] mit einem zentrierten Ikosaeder aus 13 Goldatomen 6. Dem gegenüber stehen umfangreiche Arbeiten zur Chemie der Gold‐ und Goldchalkogen‐Cluster 7–10.…”

“…Die Au 8 As 4 ‐Kette ist aus zwei Au 3 As‐Tetraedern und zwei sich durchdringenden Au 2 As 2 ‐Tetraedern aufgebaut, die sich als gemeinsame Kante die Bindung As1‐As2 der As 2 n Pr 2 ‐Gruppe teilen. Die Bildung von Liganden mit As‐As‐Bindung durch Redoxreaktionen wurde schon für Arsenidcluster der übrigen Münzmetalle beobachtet 2…”
