The asymmetric unit of the title compound, [Ag(NO(2))(C(14)H(14)N(4))](n), contains half of the repeating formula unit (Z' = 1/2). The Ag(I) ion lies on a twofold rotation axis. The primary structure consists of a one-dimensional coordination polymer formed by the Ag(I) ions and the bipyridyl azine ligand in which there is an inversion center at the mid-point of the N-N bond. The nitrite anion inter-acts with the Ag(I) ion through a chelating μ(2) inter-action involving both O atoms. In the crystal, the coordination chains are parallel and inter-act through Ag⋯π [3.220 (2) Å] and π-π [3.489 (3) Å] inter-actions.
