A new silver(I) nitrate complex of 2-(2-aminoethyl)pyridine (aepy), [Ag-2(mu-NO3)(2)(mu-aepy)(2)](n), has been synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffractometry. Two silver(l) ions are doubly bridged by two bidentate aepy ligands forming dimeric building block [Ag-2(mu-aepy)(2)] units with a Ag (...) Ag distance of 3.0587(17) angstrom. These dimeric units are further doubly bridged by two nitrato ligands into a one-dimensional polymeric chain. The nitrato ligand exhibits an uncommon bidentate bridging mode of Ag-ONO-Ag. The title complex features a hydrogen bonded two-dimensional supramolecular framework formed via N-H (...) O hydrogen bonds, involving the uncoordinated O atom of the nitrate ligand and amine hydrogen atoms of aepy. The thermal stability of the title complex was investigated using thermogravimetry and differential thermal analysis.
