Abstract: In the title complex, [Ag(NO₃)(C₅H₅NO)]_n, the Ag^I atom is coordinated by two O atoms from two different 4-pyridone ligands and two O atoms from one nitrate anion, displaying a nearly planar coordination geometry. The O atoms of two 4-pyridone ligands bridge two symmetrically related AgNO₃ units, forming a dimer, with an AgAg separation of 3.680 (2) Å. Neighbouring dimers are linked into an infinite chain through weak AgO interactions [2.765 (2) Å], AgAg interactions [3.1511 (4) Å] and - stacking interactions [centroid-centroid distance = 3.623 (4) Å]. N-HO and C-HO hydrogen bonds assemble these chains into a three-dimensional network.
