- Abstract
The coordination behavior of metal ions coordinated with heterocyclic sulfonic acid is of great significance for the construction of functional sulfonate polymers and the exploration of their potential application. In this study, two novel Ag(I)-based supramolecular structures, namely {[Ag2(4,4′-bipy)2][Ag2(P–SO3)4]·H2O}n (1) and {[Ag(dpp)](P–SO3)·H2O}n (2) (4,4′-bipy = 4,4′-bipyridine, dpp = 1,3-di(4-pyridyl)propane, and P–SO3H = pyrazine sulfonic acid) are synthesized using bis(pyridyl) ancillary ligands to assist the P–SO3H main ligand by the solvent evaporation method. The single crystal X-ray diffraction data indicate that the as-synthesized polymers belong to P-1 and P21/n space groups, respectively. In particular, the application of bis(pyridyl) ancillary ligands specifically improves the rigidity and coordination ability of pyrazine sulfonate, and then, it combines with the generated weak interaction to further extend the structure to higher dimensions. Powder X-ray diffraction results and related data, including Raman spectra, thermal stability and solid-state fluorescence characterizations, are also discussed.
