Abstract

Several AgI 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 AgI ions and four 4-PDS N-donor ligands, and show inclusion of the counter anions in their chiral cavities. The AgI 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 AgI 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.
