New tetranuclear supramolecular precursors [(R-C≡C-C≡C)Ag]4(PPh3)4 (R = iPr and chx) are employed to construct three pentanuclear 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 clusters 1−3
