Binuclear oxidative addition of Sb-Cl bonds : a facile synthetic route to main group transition element clusters and rings
Binuclear oxidative addition of Sb–Cl bonds with the clusters Os3(CO)11(NCCH3), 1, or Os3(CO)10(NCCH3)2, 2, was found to be an effective synthetic route to organometallic clusters and rings containing μ2-SbPh2 or μ3-SbPh ...
Stibine-protected Au 13 nanoclusters : syntheses, properties and facile conversion to GSH-protected Au 25 nanocluster
Monostibine-protected ionic Au13 nanoclusters, namely, [Au13(L)8(Cl)4][Cl] (L= SbPh3, 2a·Cl; Sb(p-tolyl)3, 2b·Cl) were prepared by the direct reduction of Au(L)Cl with NaBH4 in dichloromethane. Anion exchange with 2a·Cl ...
The metallostibine Os2(CO)8(μ-SbPh) : a versatile donor precursor for antimony-containing heterometallic clusters
The metallostibine Os2(CO)8(μ-SbPh), 2, acts as a good two-electron donor ligand, reacting readily with Group 8 metal carbonyls to give heterometallic clusters. Specifically, it undergoes ligand substitution reaction with ...
Oxidative addition across Sb–H and Sb–Sb bonds by an osmium carbonyl cluster : trapping the intermediate
The cluster Os3(CO)11(NCCH3) oxidatively adds across the Sb–H bond in SbPh2H to afford the clusters Os3(CO)11(H)(μ-SbPh2) and Os3(CO)11(μ-H)(μ-SbPh2)Os3(CO)11. Similarly, its reaction with Sb2Ph4 afforded Os3(CO)11(μ-SbP ...
Synthesis and Reactivity of Ruthenium-Antimony Carbonyl Clusters
The reaction of Na[HRu3(CO)11] (2) with SbPh2Cl in dry tetrahydrofuran (THF) afforded the cluster Ru3(CO)10(μ-H)(μ-SbPh2) (3); in dry dichloromethane (DCM), the six-membered ring Ru6(CO)20(μ-H)2(μ-SbPh2)2 (4) was obtained ...
