In the structure of the title compound, 2[Ag(C10H8N2)(H2O)](C7H6NO2)(NO3)·H2O, the AgI atom is three-coordinated in a T-shaped configuration by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) ligands at short distances and by one water O atom at a longer distance. Each bipy ligand bridges two neighbouring AgI atoms, forming a chain structure extending parallel to [101]. The complete 4-aminobenzoate anion, the nitrate anion and the uncoordinated water molecule are located on mirror planes: together with the coordinated water molecule, they form N-H...O, O-H...O and O-H...N hydrogen bonds, stabilizing the crystal structure.
