catena-Poly[[(nitrito-κ(2) O,O′)silver(I)]-μ-1,2-bis­[1-(pyridin-4-yl)ethyl­idene]hydrazine-κ(2) N:N′]

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 inter­acts with the Ag(I) ion through a chelating μ(2) inter­action involving both O atoms. In the crystal, the coordination chains are parallel and inter­act through Ag⋯π [3.220 (2) Å] and π–π [3.489 (3) Å] inter­actions.
