In this paper, ten new silver compounds, namely [Ag(bipy)](L1)·H2O (1), [Ag(bipy)](L2)·2H2O (2), [Ag2(bipy)2(H2O)2](L3)·H2O (3), [Ag(L4)(bipy)]·H2O (4), [Ag(L5)(bipy)] (5), [Ag(L6)(bipy)]·0.5CH3CN (6), [Ag3(L7)2(bipy)2]·2(H2O) (7), [Ag2(L8)(bipy)1.5(H2O)]·H2O (8), [Ag2(L9)(bipy)2(H2O)2] (9) and [Ag3(L10)(bipy)2][(bipy)(H2O)2]·(H2O)3.5 (10) (where bipy = 4,4â²-bipyridine, L1 = 6-amino-1-naphthalenesulfonate anion, L2 = 2-naphthalenesulfonate anion, L3 = sulfosalicylate anion, L4 = p-aminobenzenesulfonate anion, L5 = 4-dimethyaminoazobenzenen-4â²-sulfonate anion, L6 = 2,5-dichloro-4-amino-benzenesulfonate anion, L7 = 8-hydroxyquinoline-5-sulfonate anion, L8 = 2-nitroso-1-naphthol-4-sulfonate anion, L9 = 2,6-naphthalenedisulfonate anion and L10 = 1,3,5-naphthalenetrisulfonate anion), have been synthesized and characterized by elemental analyses, IR spectroscopy and X-ray crystallography. In compounds 1â6, Ag(I) centers are linked by bipy ligands to form 1D Agâbipy chain structures, in which the sulfonate anions of compounds 1â3 act as counter ions. The sulfonate anions of compounds 4 and 5 connect Agâbipy chains to form 1D double chain structures, respectively. The sulfonate anions of compound 6 connect Agâbipy chains to form a 2D layer structure. Unexpectedly, compound 7 shows a hinged chain structure, and these chains interlace with each other through hydrogen bonds and ÏâÏ interactions to generate a 3D structure with channels along the c axis. Compounds 8 and 9 show 1D ladder-like structures. In compound 10, the Agâbipy chains are connected by sulfonate anions to generate a 3D poly-threaded network, in which an isolated Agâbipy chain is inserted. The results indicate that the anionic sulfonate-containing co-ligands play an important role in the final structures of the Ag(I) complexes. Additionally, the luminescent properties of these compounds were also studied.
