Au Nanocluster Featuring a V-Shaped Alkynyl--Gold Motif.
A novel Au nanocluster with a composition of [Au(PhC≡C)(Hdppa)](SbF) was synthesized (Hdppa = N,N-bis(diphenylphosphino)amine). Single crystal X-ray structural analysis reveals that the cluster comprises a centered icosahedral Au core hugged by three V-shaped PhC≡C--Au--C≡C(Ph)--Au--C≡CPh motifs. Su...

Single crystal X-ray structural analysis reveals that the cluster comprises a centered icosahedral Au core hugged by three V-shaped PhC≡C--Au--C≡C(Ph)--Au--C≡CPh motifs. Such motif is observed for the first time in an alkynyl-protected gold nanocluster. The Au cluster shows two main optical-absorption bands at 1.25 and 2.25 eV, confirmed by time-dependent density functional theory. Orbital analysis indicates that PhC≡C -- groups can actively participate in the frontier orbitals of the whole cluster. The new Au19 cluster and the novel alkynyl--gold motif open the door to understanding the alkynyl--gold interface and discovering many potential members of this new class of gold clusters. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2015 holdings: @attributes: islocal: N |
