In the structure of the title compound, 2[Ag(C₁₀H₈N₂)(H₂O)](C₇H₆NO₂)(NO₃)·H₂O, the Ag^I 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 Ag^I 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-HO, O-HO and O-HN hydrogen bonds, stabilizing the crystal structure.
