Abstract

In the title complex, [Ag(NO3)(C5H5NO)]n, the AgI 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 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.
