| Abstract: | The reaction of AgNO3 with combinations of 1,3-bis(4-pyridyl)propane (bpp), pyridine-3,5-dicarboxylic acid (H2pdc), oxybis(benzoic acid) (H2oba), and 4,4′-oxidiphthalic acid (H4odpt) in aqueous alcohol/ammonia at room temperature produces crystals of Ag2(bpp)2](pdc)·8H2O, Ag2(bpp)2(H2O)](oba)·5H2O, and Ag2(bpp)2(H2O)2](odpt)·2H2O. All three complexes consist of 1D infinite silver-bpp cationic chains, interspersed with organic carboxylate anions that provide charge compensation in the crystal structures. The lattice water molecules are situated among the framework of the crystal structure and show rich hydrogen-bonding interactions, which serve to orientate the organic carboxylate anions in the crystal packing, while the presence of Ag···N and Ag···Ag contacts strengthens the frameworks. The luminescent properties of the complexes have been investigated. |
