Several Ag-1 coordination polymers linked by the -S-S-bridged ligand 4-PDS (=4,4'-dipyridyldisulfide)were prepared and their crystal structures characterized. The isomorphous complexes [Ag(4-PDS)(2).PF6] 1 and [Ag(4-PDS)(2).ClO4] 2 have twisted rhomboidal frameworks that consist of four Ag-1 ions and four 4-PDS N-donor ligands. and show inclusion of the counter anions in their chiral cavities. The Ag-1 ion has a tetrahedral coordination, and the rhomboidal units are assembled in the form of a 2-D sheet structure. The complex [Ag(4-PDS).OTs] 3 (where OTs- = p-toluenesulfonate) shows a 2-D sheet structure, constructed from 1-D zigzag chains bridged by interchain Ag-Ag interactions. The Ag-1 ion has a T-shaped coordination environment, and the OTs- anions are located between the sheets. The complex [Ag(4-PDS).NO3.(CH3CN)(0.5)] 4 is a 1-D zigzag coordination polymer with a chiral chain structure, incorporating acetonitrile as a guest molecule between the chains.
