catena-Poly[[[aqua­silver(I)]-μ-4,4′-bipyridine-κ(2) N:N′] 4-amino­benzoate nitrate hydrate]

In the structure of the title compound, 2[Ag(C(10)H(8)N(2))(H(2)O)](C(7)H(6)NO(2))(NO(3))·H(2)O, 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—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds, stabilizing the crystal structure.
