catena-Poly[[(nitrato-κ(2) O,O′)silver(I)]-μ(3)-4-pyridone-κ(3) O:O:O]

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 inter­actions [2.765 (2) Å], Ag⋯Ag inter­actions [3.1511 (4) Å] and π–π stacking inter­actions [centroid–centroid distance = 3.623 (4) Å]. N—H⋯O and C—H⋯O hydrogen bonds assemble these chains into a three-dimensional network.
