Both title compounds are polynuclear polymeric complexes with binuclear units. In the former compound, [Ag2(C8H7O2)2(C10H9N3)]n, the two AgI atoms display distorted square-planar coordinations. This compound contains a twofold axis and a crystallographic inversion centre, and di-2-pyridylamine (DPA) ligands crosslink adjacent binuclear units to form infinite polymeric chains. Crystal packing is stabilized by van der Waals inter­actions and partial [pi]-[pi] stacking inter­actions between the chains. The latter compound, [Ag2(C7H4NO4)2(C10H9N3)]n, contains crystallographic inversion centres and the two AgI atoms exhibit two types of distorted square-pyramidal coordination. Ag-Ag argentophilic inter­actions and Ag-O crosslinking between adjacent binuclear units contribute to form infinite polymeric chains. Weak [pi]-[pi] stacking inter­actions are observed in the polymer chain. Crystal packing is stabilized by C-H...O hydrogen bonds and by weak [pi]-[pi] stacking inter­actions.
