Abstract

In the title one-dimensional coordination polymer, [Ag(NO3)(C12H6N2O2)]n, the AgI atom is penta­coordinated by two N atoms from a 1,10-phenanthroline-5,6-dione (phen-dione) ligand, one O atom from the nitrate anion and two O atoms from another phen-dione ligand. The coordination environment around silver is slightly distorted square-pyramidal. Inter­estingly, the Ag—O distances to the phen-dione ligand are different [Ag—O = 2.612 (6) and 2.470 (5) Å]. The one-dimensional chains run parallel to [101] and are further inter­connected by weak hydrogen bonds (C—H⋯O) and π–π stacking inter­actions [centroid–centroid distances 3.950 (4) and 3.792 (4) Å], forming a three-dimensional supra­molecular network.
