4,4′-Bipyridine and bis(4-pyridyl)propane as bridging ligands in the supramolecular assembly of silver(I) polyhedra containing embedded acetylenediide

Six new double salts of silver(I) acetylenediide, namely [Ag13(C2)2(CF3CO2)9(bipy)4(H2O)3] (1), [Ag18(C2)2(C2F5CO2)18(bipyH)4] · 3H2O (2), [Ag6(C2)(CF3CO2)4(bpp)] (3), [Ag6(C2)(C2F5CO2)5(bppH)]n (4), [Ag6(C2)(CF3CO2)5(bppH)]n (5) and [Ag23(C2)4(CF3CO2)15(bpp)6] · H2O (6) (bipy = 4,4′-bipyridine, bpp = bis(4-pyridyl)propane), have been shown to exhibit a variety of discrete and higher-dimensional supramolecular architectures.
