Abstract: Reactions of AgClO 4, Zn(CH 3COO) 2· H 2O and CuI with the ligand 4,4′-dipyridylsulfide (dps) in 1:1 ratio give rise to coordination polymers 1-3 and 5, the structures of which were characterized by X-ray crystallography. Polymers [Ag 2(dps) 2](ClO 4) 2·-MeCN (1) and [Ag 2(dps) 2(μ 2-MeCN)(MeCN)](ClO 4) 2·MeCN·H 2O (2) are pseudo-supramolecular isomers, differing from each other in the coordination geometry of silver atom and the packing pattern. Both 1 and 2 are zigzag coordination polymers bridged by weak Ag⋯Ag, Ag⋯S or Ag⋯N≡C-CH 3 interactions to form double stranded coordination polymers. While [Zn(dps)(CH 3COO) 2] (3) is a zigzag single stranded coordination polymer, [Zn(dps) 2(H 2O) 2](ClO 4) 2·H 2O (4) is an unusual mononuclear complex with a box-like structure. Interesting intermolecular hydrogen bonding present in the compounds 3 and 4 leads to 3D hydrogen-bonded network structure.Coordination polymer [Cu 2I 2(dps) 2] (5) is a non-interpenetrating (4,4) net. Photoluminescence properties of the compounds 1-5 have been examined in solid states at room temperature. These compounds have been found to exhibit yellow and blue photoluminescence. © 2004 Elsevier B.V. All rights reserved.
