Unprecedented coordination chemistry of a chloro(phosphine)gold(I) complex: [(Ad2BnP)2Au][AuCl2]

Gold(I) Complexes Bearing P∩N-Ligands: An Unprecedented Twelve-membered Ring Structure Stabilized by Aurophilic Interactions

“…Usually, the gold(I) atoms are linearly coordinated by the phosphorus and halogen atoms forming a neutral complex. Up to now, the only example of a 1 : 1 complex with an ionic structure is [(Ad 2 BnP) 2 Au][AuCl 2 ] (Ad = 1-adamantyl, Bn = benzyl) [34]. Single crystals of the gold complexes 6, 7, 9, and 10 were grown from CH 2 Cl 2 /Et 2 O.…”

Synthese und Kristallstruktur des Komplexsalzes [Au(tBu2PH)2][HCl2] / Synthesis and Crystal Structure of the Complex Salt [Au(tBu2PH)2][HCl2]

“…Während in Reaktionen von [MCl( t Bu 2 PH) 3 ] ( M = Rh, Ir) mit [Ru 3 (CO) 12 ] heteronukleare Metallcluster mit µ-P t Bu 2 -Liganden gebildet wurden, koordinierte der sekundäre Phosphanligand in der analogen Reaktion des Metallcarbonyls mit dem Einkernkomplex [AuCl( t Bu 2 PH)] (1) in unveränderter Form am durch Clustererweiterung eingebauten Goldatom. Es bildete sich so der chlorido-verbrückte Metallcluster [Ru 3 Au(µ-Cl)(CO) 10 ( t Bu 2 PH)] mit intaktem sekundären Phosphanliganden [3].…”

Synthesis, Characterization and Luminescence of Silver(I) and Gold(I) Complexes Bearing a Diethyl Acetal Functionalized N-Heterocyclic Carbene

“…3). Interestingly, the Au1···C1 i distance of 3.498(1)Å is significantly shorter than the Au···Au distance and in the range of reported π(C)-Au(I) interactions [12]. Therefore, it is tempting to speculate that the dimerization is synergetically governed by both closed-shell d 10 -d 10 as well as cation-π interactions.…”
