title: catena-Poly[[(nitrato-κO,O')silver(I)]-μ(3)-4-pyridone-κO:O:O].
abstract: In the title complex, [Ag(NO(3))(C(5)H(5)NO)](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 AgNO(3) units, forming a dimer, with an Ag⋯Ag separation of 3.680 (2) Å. Neighbouring dimers are linked into an infinite chain through weak Ag⋯O inter-actions [2.765 (2) Å], Ag⋯Ag inter-actions [3.1511 (4) Å] and π-π stacking inter-actions [centroid-centroid distance = 3.623 (4) Å]. N-H⋯O and C-H⋯O hydrogen bonds assemble these chains into a three-dimensional network.
