In the title compound, [Ag(C12H9ClN2O)2]NO3, two N atoms from two pyridine rings of two N-(4-chlorophenyl)pyridine-3-carboxamide ligands coordinate to the AgI atom, forming a nearly linear geometry with an N-Ag-N angle of 173.41 (7)°. The crystal structure is stabilized by N-HO, C-HO and C-HCl hydrogen bonds and - stacking interactions [centroid-centroid distance = 3.5469 (16) Å] between the pyridyl and benzene rings. The shortest AgAg distance is 3.2574 (5) Å.
