Bidentate Phosphine-Assisted Synthesis of an All-Alkynyl-Protected Ag Nanocluster.
Determining the total structure of metal nanoparticles is vital to understand their properties. In this work, the first all-alkynyl-protected Ag nanocluster, Ag(C?CPh), was synthesized and structurally characterized by single crystal diffraction. Ag atoms are arranged in a Ag@Ag@Ag three shell struc...

In this work, the first all-alkynyl-protected Ag nanocluster, Ag(C?CPh), was synthesized and structurally characterized by single crystal diffraction. Ag atoms are arranged in a Ag@Ag@Ag three shell structure and all 44 phenylethynyl ligands coordinated with Ag in a µ mode. In spite of being absent in nanocluster, P NMR study reveals that bidentate phosphine first reacts with Ag(I) to form a dinuclear complex, from which Ag atoms are then released to phenylethynyl ligands. This phosphine mediated strategy may find general application in synthesis of alkynyl-protected Ag nanoclusters. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2017 holdings: @attributes: islocal: N |
