Wu H, Dong XW, Liu HY, Ma JF, Li SL, Yang J, Liu YY, Su ZM: Influence of anionic sulfonate-containing co-ligands on the solid structures of silver complexes supported by 4,4'-bipyridine bridges. Dalton Trans. 2008 Oct 21;(39):5331-41. Epub 2008 Aug 18.
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 = 4,4'-bipyridine, L1 = 6-amino-1-naphthalenesulfonate anion, L2 = 2-naphthalenesulfonate anion, L3 = sulfosalicylate anion, L4 = p-aminobenzenesulfonate anion, L5 = 4-dimethyaminoazobenzenen-4'-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 1-6, Ag (I) centers are linked by bipy ligands to form 1D Ag-bipy chain structures, in which the sulfonate anions of compounds 1-3 act as counter ions. The sulfonate anions of compounds 4 and 5 connect Ag-bipy chains to form 1D double chain structures, respectively. The sulfonate anions of compound 6 connect Ag-bipy 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 pi-pi 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 Ag-bipy chains are connected by sulfonate anions to generate a 3D poly-threaded network, in which an isolated Ag-bipy 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. |
