Abstract

Abstract : Supramolecular precursors [(R–CC–CC)Ag]4 (PPh3 )4 (R = iPr and chx) are employed to construct three iso-structural silver(i ) alkyl-1, 3-diynyl cluster complexes that bear the same novel trigonal bipyramidal Ag5 core. Abstract : New tetranuclear supramolecular precursors [(R–CC–CC)Ag(PPh3 )]4 (R = iPr and chx) are employed to construct three polynuclear silver(i ) alkyl-1, 3-diynyl cluster complexes (1–3 ) that bear the same novel trigonal bipyramidal Ag5 core consolidated by silver–ethynide and argentophilic interactions. The present results strongly suggest that the assembly of high-symmetry medium-nuclearity clusters1–3 is initiated by the accretion of additional Ag(i ) ions by the Ag4 template of the precursors through argentophilic (<3.4 Å) interaction, and demonstrate that core transformation is an effective synthetic route to high-symmetry metal clusters.
