The anions do not coordinate to the Ag(I) atoms and only act as counterions in complexes 1-3. Due to the anions, different H bonding systems are found in those three compounds, resulting in the different crystal packing. Through H bonding interactions, the structures of complexes 1-3 display a double layer, a three-dimensional framework and a novel double chain, resp. In complex 4, the HBDC- anions act not only as a counterion, but also as bridging ligands, which lead the zigzag [Ag2(PyBIm)2]∞ chain into a two-dimensional undulating sheet. The sheets are connected through H-bonding as well as π-π interactions into a three-dimensional framework. The thermal stabilities of the four complexes and anion exchange properties of complexes 2 and 3 were also studied.
