| Abstract: | The crystal structure of an organosulfonate ligand 2-aminopyridine-5-sulfonic acid is reported here. Reaction of AgNO3 and the 2-aminopyridine-5-sulfonic acid in basic ethanol/aqueous solution gave [Ag(C5H5N2O3S)] n (1). X-ray crystallographic study reveals that 1 is a 2D network structure constructed by strong Ag-pyridine, Ag–NH2 interactions and weaker Ag-sulfonate interactions. The replacement of the benzene ring by the pyridine ring causes the coordination modes of the sulfonate group to change from μ 3 to μ2. Its TG/DSC property is also discussed. |
